I have a stand alone java program that opens a text file in UTF-8 mode and read each line in the file containing Swedish characters like å, ä, ö. The text file has been saved in utf-8 mode. The java program prints what it reads from the file into standard output and I have verified that the program can read and print these special characters properly. The program then saves this data it read from the file into a Mysql 5.5 database with default utf-8 collation by using a JDBC connection.
Nevertheless, when the program inserts these textual data with the Swedish characters into the mysql database, the special characters are replaced with weird black characters that are not readable. If I change the database collation to latin1 instead, then all these special characters are removed by the MySQL server. I have googled the issue and found suggestions involving the use variations of utf-8 and latin1 as the default database collation but non of them seems to have helped me so far.
I wonder if there is anyone facing a similar issue on placing Swedish characters in a mysql database? If so, could you tell me what is the collation type and charset I should be using to have swedish charecters correctly in the database. Do I have to make a specific setting in JDBC database connection for these letters to be saved correctly? Perhaps the issue is more java related but I verified visually that my java program can read/print these characters properly. Thanks.

I have a Java Swing application for a client that works internationally. A few times per year a piece of text is copied from a Microsoft application like Outlook into a JTextArea, and then stored in a UTF-8 database. Upon retrieval, the database throws an SQL exception that it can't decode some character.
I'm trying to comprehend the copy-paste part of the process. Is there any information about how copying from windows to Java works exactly? Can't find it.
Windows is setup using CP1252, but the text in Outlook definitely is using non CP1252 characters, so the copied data has an encoding. And when that is pasted into JTextArea, does Java transcode that to UTF-16 (it's internal string encoding)?
I am new to JAVA. I wanted a JAVA code to convert a text file coming from Unix to a text file that goes to Linux server. So, its a character conversion code from UTF-16 TO UTF-8. The text file goes tthrough oracle database before it reaches linux server. I need this conversion because some special symbols are getting converted to garbage values. Please help Java Experts :)
I'm having troubles with special characters like í, ó, ñ, and so on in my MYSQL database.
I've read a lot about character set, collation, utf and son on but I might not being able to proper apply it to this problem. I'm not sure if the problem is with my tables or when reading the source file and encoding. I'm working on netbeans developing an interface that generates specific reports
Here I briefly explain the process when the issue occurs
There is a table where are located the path files for the Excel files that are requested.
My code takes that path, opens the file using the JXL library.
Then it starts reading every cell that it is indicated in the code and export the data to the tables indicated (HERE IS WHERE IN THE TABLES APPEARS THIS � IN EVERY SPECIAL CHARACTER)
The data is correctly exported to the several tables, and there is no problem with that, only special characters that are replaced with this �
So, after researching I've tried this
As I'm using MYSQL workbench I've alter every table in the collation from utf8 - default TO utf8 - utf8_spanish_ci and utf8 - utf8_spanish_ci
I've tried also changing the collation to utf16 - default collation, utf_spanish_ci, bin, etc
And also, I've tried using the utf32 collation.
The netbeans encoding it is correctly set to utf-8
I've tried exploring the JAVA functions that connects to MYSQL, I'm using this connection but I haven't found nothing about encoding:
private Connection conecta=null;
String Driver="com.mysql.jdbc.Driver";
String Url="jdbc:mysql://XXX.XXX.XXX.XX/BLAABLA";
Class.forName(Driver);
conecta=DriverManager.getConnection(Url,User,Password);
The database when I manually insert data that contains special characters, it correctly displays whenever I need it, but when I try using the automatically insert option as previously described that reads the file using jxl library and so on, then it happens the � thing.
I've found some useful answers here in stackoverflow but all are related to specific cases of php, html, xml and so on. All the answers about java are related to the utf8 collation
So I hope you can provide me some help.
Am I not doing the collation correctly?, Should I try something weird directly in the console? Does mysql workbench is forbidding something?
I'm open to all kind of suggestions but if the answer is like "You must use another library because jxl does not work with that" please consider that my project is almost done, and re-do this with a different library could take me much more time as I already have expected. Please, if JXL is the problem probably there must be something else. Nothing is impossible right?
Thanks for the time.
Excel files by default uses windows-1255 (Cp1255) codification. So when you read those bytes from the excel file you need to treat them with that charset and then store them with utf8.
I need some help. I have to read data from a file and store it into an Oracle db. I run into troubles when characters like 'à' or 'À' appear into data. For example, 'à' is read and become 'Ã ' into my application, so, when I try to save data into db, sometimes, the db complains about values too big about the field that are going to save into. I also tryied
Normalizer.normalize(row, Form.NFD).replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
I payed attention about encoding too. I notice that if I run my application on data file, a Cp1252 file, on a Windows machine I got no errors. Sadly I got errors when I run the stuff on a Linux machine. I'm using java 6. TIA.
So, the default character encoding on your windows machine is probably windows-1252 (a superset of latin-1). That means that if you don't specify the charset when reading in the file, Java will default to your system default and get it right.
On your Linux machine, your default charset is probably UTF-8. That means that if you don't not explicitly specify a charset while reading a file, it will default to UTF-8 . . . which, in this case, is wrong.
You didn't post how you're reading in your file, but for example:
InputStreamReader isr = new InputStreamReader(file, "UTF-8");
This would create an input stream reader for reading a file formatted in UTF-8.
I am building an app that takes information from java and builds an excel spreadsheet. Some of the information contains international characters. I am having an issue when Russian characters, for example, are rendered correctly in Java, but when I send those characters to Excel, they are not rendered properly. I initially thought the issue was an encoding problem, but I am now thinking that the problem is simply not have the Russian language pack loaded on my Windows 7 machine.
I need to know if there is a way for a Java application to "force" Excel to show international characters.
Thanks
Check the file encoding you're using is characters don't show up. Java defaults to platform native encoding (Win-1252 for Windows) instead of UTF-8. You can explicitly set the writers to use UTF-8 or Cyrillic encoding.
