I wish to develop a client-server application in VB.NET. I want to store some fields in
Unicode. As per MySQL documentation I tried the fields with varchar and charset UTF-8 for storing Unicode data.
I could insert data using the MySQL connector command object but when I try to display data in datagridview some junk is appearing.
What am I missing?
I don't know VB.NET, but you should have the possibility to set the encoding of the database connection from your application to MySQL when setting up to connection. Is that part set to UTF-8 as well?
Alternatively you can try issuing the following MySQL command after you connect:
SET NAMES utf8

I need to insert some data into a MySQL table. The table has collation utf8_general_ci. The insert lines are all written into a text document.
I am able to insert special symbols into the MySQL tables on my own computer when I copy-paste the inserts into the HeidiSQL editor and execute from there.
Now I need to insert them into the database on the server. I am using Webfaction. I don't seem to be able to get the symbols in there. Instead, the database inserts them as a '' (empty string). I upload the text file (using Filezilla), ssh to the server (putty), and then execute the inserts from MySQL as "source path/file.txt". The encoding of the file before uploading doesn't seem to make a difference (ansi or utf8).
i been seeing lots of encoding related issues the owner should google a bit before posting
general check list:
mysql table schema to use utf-8
mysql clients connection to use utf-8 mysql --default-character-set=utf8
php mysqli_set_charset to utf-8
html encoding to utf-8
putty, emac clients... to be in utf-8
I have a mysql DB contains arabic data. when opening the db via mysql workbench the data looks like "ßÇÙã ÇáÌãÇÓí".
when making a simple php file that read from the DB the data looks fine(arabic).
but when reading the data via ASP.net the data looks like "ßÇÙã ÇáÌãÇÓí".
Please help me.
Before running SELECT query from your ASP.net application try running two queries after you connect to the database:
SET CHARACTER SET 'utf8';
SET NAMES utf8;
Basically you need to make your app aware of possible international characters.
P.S. This should be run again every time connection is established, e.g. you can't run it once from MySQL workbench and fix your app. Your app need to do that on its own.
I'm encoding all my files in UTF-8 without BOM.
All characters appear correctly when displaying my page, yet values retrieved from my MySQL database such as Árbol render Ás and nont ANSI characters incorrectly (as a black romboid). I'm storing values in database with PHP My Admin manually.
What can be causing this issue with the database? Are there any changes I must do to make the database "utf8-ready"?
After you connect to the server, use the following command to view your current client characterset:
status;
To set it, use the following command:
set names utf8;
I have an API running on Sinatra. It queries a mysql databases, and returns data in json or xml format. I'm having a problem with unicode data. If I query the production database from the console, I'll get data correctly:
persönlichen
However, in my API results (or if I were to query the database in irb using the mysql2 gem), I get this:
persönlichen
Everything works swimmingly on my development box, which is confounding my efforts to solve the problem.
I have done everything I can to make sure that the database is utf-8 only (encodings, collations, client and server character sets are all utf-8). I'm using the mysql2 driver, which supposedly forces everything to utf-8. I'm setting :encoding => 'UTF8' on my active record connection.
What am I missing?
I was able to nail the problem down - the data wasn't encoded correctly in the database. I was populating my database using a sql dump file - I added this to the top, and everything worked great:
set names utf8;
create database if not exists `my_db_name` CHARACTER SET utf8 COLLATE utf8_general_ci;
my mysql db has character encoding utf8. In QueryBrowser i can see special characters are correct. In appplication using openjpa i can see the same values also correct.
But when I persist object into DB, I have correct values in application but incorrect in DB!
When I restart application that special characters in application are incorrect.(as they are picked from DB)
All is set to UTF-8, java application works well, reading data from DB is correct but problem is when openjpa stores values in DB, they turn into '?'.
Any ideas? Thanks
Check your encoding on the MySql server configuration level (my.cnf file), and also on the level of a specific database. Once, I had similar issue when these two options has been set to different values (encodings).
