Re: Mysql upgrading to RT3.8 gives you garbled UTF8 text
[In reply to]
|
|
I'm having trouble with UTF8 text in 3.8.0 too.
Ruslans patched fixed the special chars in queue names and ticket subjects.
However when viewing tickets, UTF8 text in the email text is still wrong.
But if i click reply/comment on the post, text is shown correctly in the
editor (i'm using the WYSIWYG FCKeditor)
Any idea of what i could patch ?

>>> Older RT versions were not using any connection adjustments like SET NAMES or SET CHARACTER SET and most users had latin-1 as default mysql charset. RT was storing UTF-8 data into latin-1 columns what is theoretically wrong, but practically works fine. In 3.8 we have to properly define columns as binary, UTF-8 or ascii as actually they do contain only this data. MySQL's doc clearly says that the only way is to convert field to some binary format (no data change) and then to required character set. All these is described in comments in the beginning of the script.
