Hi Sergiu,

Maybe the modif I did on my instance did solve the problem. If not, then it's related to java-mysql connection...

see XWIKI-951

Hi Ning,

I also have a utf8 instance and I cannot reproduce your bug even when mixing French and Japanese characters. I'm using postgres though, but mysql qhould work also.

However, I can reproduce this, on a fully UTF-8 system: OS, disk, database, XWiki settings.

It seems that when working with the document archive the characters are broken. In the database everything is OK, so it's something internal.

When did you set up your wiki to use UTF8 characters ? Maybe you created the database with an ISO Latin 1 encoding and then change your wiki encoding after the DB creation ?

What happens when you ask to see the modifications between the current version and an older one ? Do you correctly see the chinese chars of the older version ?

And by the way, Sergiu, I think the velocity.properties parameter are just useless (as far as I could test) as the velocity macros are called using Strings and not using InputStreams, in fact, it could hurt a little when reading the xxx.vm files that are not encoded in UTF-8 (see discussion on the encoding of the code base...).

Indeed, I did not notice anything when changing this. But I don't know what internal stuff might break if I don't set this.

I think that this only affect the way .vm files stored on the disk are read, but these files are plain ASCII.

Regards, Gilles,

I do everything you said. And I make sure that all encoding is UTF-8 or utf8.
But I'm sad to find that it does not work, still "?????" when roll back.

Some ideas:

* Check that the tables are really using UTF-8: get a mysql shell, open the xwiki database and type "select charset(xwd_content from xwikidoc;". If it does not say UTF-8, then you need to change the encoding. I've attached a script that tries to do that (and creates indexes, too)

* Check that the mysql connections are set to UTF-8. "show variables like 'character_set%';". If it says something else, you can either globally set the mysql encoding to utf-8 (in the mysql configuration file, search the mysql documentation), or configure hibernate to request this:
<xwiki-dir>/WEB-INF/hibernate.cfg.xml, add
    <property name="connection.characterEncoding">utf8</property>
after:
    <property name="connection.driver_class">com.mysql.jdbc.Driver </property>

* Check that you set all the encoding parameters to UTF-8:
** in WEB-INF/xwiki.cfg: xwiki.encoding=UTF-8
** in WEB-INF/ web.xml:
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
** in WEB-INF/velocity.properties:
input.encoding=UTF-8
output.encoding=UTF-8

After this, it should work just fine.
