When these PDFs are opened in browser in Google Chrome the colours are changed drastically, but when opened in another browser or opened in Preview on Mac the colours go back to normal.
It also doesnt occur in some other languages.
You can see in the screenshot below what it should display (top) and what it is displaying (bottom).
The first page consists of a single large JPEG2000 compressed image: 8 bit indexed color, 1276 x 1790 pixels.
A quick look at a comparison of browsers shows Chrome does not support JPEG2000 (officially at least, since you still got to see something).
There seem to be some plugins that add JPEG2000 support to Chrome, but
that is a local solution, it does not fix the issue for all users; and
Chrome uses its own internal PDF renderer, so it might not work "inside" PDFs.

We have a catalog on our college website.
It may be found here:
https://www.southark.edu/admissions/resources/course-catalog
The links going down the left side of the page point to specific pages within the catalog.
For example:
https://www.southark.edu/images/catalogs/2021-2022/2021-2022_SouthArk_Catalog_FINAL.pdf#page=100
But when clicked, Chrome truncates the last portion of the url (in this case, #page=100), and it displays the first page of the catalog, not the intended page.
This happens in Chrome, but not Firefox.
It has worked in Chrome for years, but now it does not.
Any idea why Chrome is doing this and what kind of workaround I might be able to do?
P.S. I just tested it in Safari on my iPhone and it is doing it on there as well.
Thanks,
Charley
I discovered that it is due to the Chrome PDF extension. If I turn it off, it operates as it should.
TL;DR
How/why are some browsers able to search and highlight text in the HTML body which is followed by #:~:text= in the URL?
Explanation
One day I was searching for something on Google, which lead me to Quora's result. I observed that 2 sentences were highlighted in yellow, which were part of URL after the aforementioned parameter. I thought this would be Quora's feature for SEO or something, however, also found this on Linkedin, and Medium, and so on.
I'd like to know:
What is this highlighting called? Why/how does it work?
This seems to be browser-specific. What kind of browsers support this?
It seems to work on Chrome and Edge; but not on Firefox, Safari, and IE.
Does a frontend programmer need to incorporate something in the code to have search engines highlight content on their web-pages? (Based on the assumption that search engines actually appends the relevant string predicted by user's query)
The highlighting is called Text Fragments. Its a new feature that was recently added to Chrome 80. It works by specifying a text snippet in the URL hash.
Yes it is browser specific.
No, the experience that you get when clicking on a link from Google's search results is part of Featured Snippets which are algorithmically determined. There is nothing you can incorporate into your code to prompt search engines to highlight text on your page.
There is no markup needed by webmasters. This happens automatically,
using Scroll To Text for HTML pages

While text fragments is natively implemented only in latest Google Chrome (and the latest versions of Chromium-based browsers, such as the new Microsoft Edge), there is a browser extension/add-on that seems to enable it on Firefox and Safari: https://github.com/GoogleChromeLabs/link-to-text-fragment
It appears to use #ref-for-fragment-directive:~:text= and additional arguments (instead of just simple #:~:text=).
Firefox: https://addons.mozilla.org/firefox/addon/link-to-text-fragment/
Safari: https://apps.apple.com/app/link-to-text-fragment/id1532224396
Curiously enough, the extension has also been made available for Chrome and Edge too (!).

UPDATE: I'm testing it on Firefox Developer Edition, and it doesn't work for me.
I have a new website with a set of favicon images auto generated from a source file using Real Favicon Generator, and there are:
9 Apple favicons
1 Android favicon
3 named favicons
1 Safari pinned SVG
1 json manifest
1 set of Microsoft tile image/colour
Obviously most of these can be placed for their respective vendors - Apple, Microsoft tiles, etc.
I have an issue in that running the website on Firefox, I want the favicon it uses to change but I do not know which one it actually uses?
I have read this question but the stated answer on here is incorrect and
Firefox and Safari will use the favicon that comes last.
is no longer true.
Obviously it's a time consuming repetition to go through ~15 images to find the one that gets changed on one browser, and I actually found that Firefox 42 selects the 96x96 dimension favicon, rather than the last one presented.
Question:
Is there a way [aside from trial and error] to load a page and then find a declaration in the browser defining which image from the HTML head is used as the page favicon in that browser?
Additional Information:
There is an incomplete reference list here. However, this misses out various versions and various OS, and I can only assume these details where found from trial and error.
While this is useful, the various links and solutions on that question give a single URL result for an automated process, such as
http://www.google.com/s2/favicons?domain=www.domain.com
Which works fine in returning a valid favicon but it does not return the favicon that my browser uses when I tested it.
Other links from that question are similar, most only returned a 16x16 favicon and many clearly did not return the image used. Some probably didn't return the image used... it is hard to differentiate 16x16px sometimes!
You can use the Compatibility test of RealFaviconGenerator. The test will ask you which icon you see. But there is a twist: the test is not really for the end-user, so you will have to right-click the image corresponding to the icon you see, inspect it, and look at the alt attribute of the img tag. But that will prevent you from playing with 20+ images to make them different. Much easier!
Full disclosure: I'm the author of RealFaviconGenerator.
Note: I would be interested in your investigations to fix the answer you mention (I'm his author).
Using the Inspect Element, or just Inspect tool, available in Firefox and Chromium. The Network tab shows all http operations related to reload. Filtering by 'favicon' most likely peeks the correct operation, when the page is reloaded.
The fact that the browser downloads an image is a strong hint of what gets displayed. Yet, doubts can persist, e.g. which part of an .ICO. Unfortunately, the tab is a computed element not visible in the (computed) page source.
On Firefox, the iconuri is visible in the json code of exported bookmarks.
[Problem] -- I am having a problem with web fonts rendering on a specific computer, other computers in my house render the text fine (same OS and browser versions). They look really bad and pix-elated I know all about differences between how browsers render things differently but its not supposed to look this bad.
[What I've Tried] -- I tried prioritizing the .svg in my CSS first on my site to fix it on Google Chrome but it did not help. I installed Firefox and discovered it too does not render the Open Sans font correctly either. I also have tried clearing my cache (I have a cache clearing plugin) and opening in a incognito window thinking a chrome extension was causing a problem but no difference. From the screen shot it appears Chrome at least renders the larger "Open Sans Condensed" but the smaller text is pixelated. Its weird a fresh install of FF also has the same problem as Chrome. Also tried downloading the font files from Google Fonts and installing them locally, no difference.
IE 11 renders the text correctly. I need trouble shooting ideas..
The screen shot below is from the official Google Fonts website located here http://www.google.com/fonts/specimen/Open+Sans#pairings so it should rule out any bad coding on my own page. The open sans font on fontsquirrel loads correctly and its not pix-elated.
Here is what I see and I don't think the fonts should look that pixelated... http://imgur.com/hwvupBq sorry too low rep to post images :(
Each browser loads the fonts using different formats. Usually you would use font-face with the four different types, EOT, WOFF, SVG AND TTF. You can use the Font Squirrel site to load your font and spit out the four different versions. Also, take a look at Google font embedding which takes care of the the work (although they will look slightly different in different browsers)
The problem ended up being that my Windows 7 machine did not have cleartype enabled. See this post to see how to enable it http://www.howtogeek.com/howto/28790/tweak-cleartype-in-windows-7/
I made a form on my WordPress site that listed a few options. When viewing the website in Chrome the text doesn't render correctly, however, it renders correctly when viewing the page via Internet Explorer.
Not too sure for the reasoning behind this. Does anybody have a clue?
Sometimes, the default font on your computer might have been overwritten expecially if your font is georgia, I most times have this problem as well, i think what you should do is find another machine running your version of chrome, preferably newly formatted without font installation and test the page. also check the encoding, [utf_8(http://en.wikipedia.org/wiki/Character_encodings_in_HTML) is the browser standard
This thread might show you how to change character encoding
