On my site I am using the Google Font Roboto. I noticed in several places the following:� or what I call a question mark in a black diamond. (Does this symbol have a name?)
I typically see this when a font doesn't have a character it can render, however, this doesn't appear to be the case in this instance. It happens in a few instance. One of them is when there is an extra space the other I have seen is when I use the § symbol.
I tested Roboto using the § symbol with a type tester and it works just fine.
Why doesn't it work on my site? What is going wrong?
I am unsure why this is happening and would still love an answer but I found a solution that I am using in the mean time.
It appears to have have happened with content that was copied into my text. For spaces or other symbols were this appears (such as - or / I am just retyping the character. For the § symbol I replaced it with the HTML character § (or you can use §) and this has solved the issue.

i want to design my own video player. I want to add this special character as a "volume"-button: 🔉 http://www.fileformat.info/info/unicode/char/1f509/index.htm. But it always shows a weird rectangle with the number 01F509.
Whats wrong ?
greetings
When you see a weird rectangle with the number 01F509, it means that the browser has correctly recognized the character but cannot display it due to lack of glyph for it. Either the system has no font containing a glyph for the character, or the character is unable to use such a font, due to a browser bug. For generalities, see my Guide to using special characters in HTML.
The Fileformat.info page cited has a link to a list of fonts that support the character. The list is short: Quivira, Segoe UI Emoji, Segoe UI Symbol, Symbola. (LastResort is not a real font.)
Segoe UI fonts are proprietary and available only in relatively new versions of Windows. Besides, there fonts exist in several version, and this character seems to be a rather recent addition.
This means that you wold need to use Quivira or Symbola as a web font (downloadable font). If you choose to do that, use e.g. http://www.fontsquirrel.com/ to generate the font files and the CSS code for using them. Note that both Quivira and Symbola rather large fonts, so using them just to get one glyph is a bit disproportionate.
At this point, it is rather obvious that some other approach is most probably better, e.g. using an image in sufficient size and reducing it according to font size by setting its height in em units.
To avoid encoding issues, try including the character in your HTML code using the hexadecimal entity notation: 🔉 then make sure that the font you are using contains this character, else you'll see a rectangle in place of the character.
You may create your own font with the desired character using tools such as http://icomoon.io
Also note that some browsers have issues displaying characters outside of the range 0000 to FFFF (plane 0 of the Basic Multilingual Plane (BMP)). I have experienced the issue with Safari on Windows and IE <= 8. So try avoiding this range if you want to support all browsers.
I am currently using the utf code "\293B" for an arrow to put before the reply link in posts. the html is declared utf 8. The arrow works in firefox and explorer but not chrome. i saw that wordpress uses content: "" ("\f412";) (for example here:http://cinematicamsterdam.wordpress.com/2014/05/26/cinematic-city-a-retrospect/) that works accross all browsers but I can't paste it in my document. How can I do it?
i'm a newbie here, sorry if the question is simple..
This does not primarily depend on browsers but on fonts installed in the system; secondarily it depends on your CSS settings and on some shortcomings in browsers. For a general description of such issues, see my Guide to using special characters in HTML.
In particular, U+293B BOTTOM ARC ANTICLOCKWISE ARROW “⤻” has rather limited font support. A large number of systems have no font containing it. It could be used rather (though not 100%) reliably using a downloadable font, but it sounds like you are generating HTML-format e-mail messages, so downloadable fonts are hardly a feasible option.
The best short appears to be to an image instead.
What your describe as WordPress usage is a Private Use codepoint. In practice it works only with a particular special font. You can copy and paste it, but outside the private use context such as use on a web page with a specific font, it has absolutely no meaning and should not be expected to have any particular rendering, or any rendering at all.
My problem can be best described by attaching these two screenshots: [1] [2]
In the second image, notice the "Continue Reading" link is rendered in sans-serif (?), and in the first image the problem is clear.
Basically, this only happens in Chrome on Windows.
So it seems like any line containing an HTML special character will have its font-family affected, and rendered in some sort of default-type fonts. I realize these custom characters may not be present in my first-choice font, but why are other characters affected as well? How can I remedy this?
If it's of any help, here's a link to my website. I'm using Ideal Sans SSm by H&FJ.
edit: It seems that my question isn't that clear after all. If you look at image [1], you can see how Chrome renders my fonts after an HTML character has been used. This is how the HTML looks like:
Especially if you’re new to OS X, this is the very first app you want to have. Holding ⌘ for a bit longer presents you with a list of active shortcuts, both global and app-specific ones. CheatSheet is also useful for existing Mac users looking to expand their shortcut vocabulary for extra effectiveness.
As seen in image [1], when this code is inserted, a different font is rendered.
Note: on my live website I currently have span tags around the special characters (that's a ⌘, by the way) in order for visitors not to suffer from this. This can actually help us with a direction towards the answer: Why is it that when the special character (any special HTML character) is wrapped in span tags, it and only it is affected by this, but when it's wrapped in span tags, the whole line is affected.
I am trying to solve an issue with Google WebFonts. I want to use font Signika from them. As you can see it has letters such as Š, Ů declared/implemented. On our website, however, it does not render these letters but just standard and in word DOMŮ - letter Ů is in another font and in word DALŠI letter Š in another font. Is there any solution for this? Should I declare some encoding for these types of letters, or where could the problem be?
When i look at your website, i see both the words (and individual letters) you list as problematic in the font Signika.
I do notice however, that you are only calling for the Standard font set, and not the Laten-Extended Subset. On this page you may want to check the box Latin Extended (latin-ext) and update your code if other browsers are experiencing problems.
If characters are implemented in the font file but your site can not display it you need to check if you are calling right subsets:
For example, to request the latin and latin-endended subsets of Oswald, the URL would be:
http://fonts.googleapis.com/css?family=Oswald&subset=latin,latin-ext
For more information:

Hope it helps.
Is it possible to render correct bar-codes in HTML using the Code 128 font?
The main content of the bar-code is fine in the broswer (firefox) but when I try to add the start code character I just get this character in the browser:
Ñ
This is ASCII code 209. I'm wondering if it even has a bar representation.
I'm using MVC but this is really just a HTML/CSS problem I think.
Thanks
This isn't quite what you asked for, but you can make barcodes using CSS: see http://unixshell.jcomeau.com/src/barcodes/memberships.html. I'm using code39 for this, but most other linear codes can be done the same way.
Are you sure that the client is going to have barcode font installed?
Server side image generation seems to be a better solution.
You may want to try Barcode.dll for barcode rendering.
It includes ASP.NET barcode control - just drag & drop.
Please note that this is a commercial product I developed.
I know this is years too late, but looking again at the question, I'm pretty sure you're just not using the right numeric code for your font. there is no single "Code 128 font". while 209 is shown by Wikipedia to be the correct "common" code for Start B, in various fonts I found online this is not the case. in this, Start B is 236; and here it's 204. use the right code for your particular font, and you should get what you want.
a code point not encoded by the barcode font will be rendered by a default font, which is why you're seeting the N tilde character.
