Summary0027411: UTF8 not working


Refering to the following post, I experience the same issue but with french caracters.

When I enter the accent "é", I get "é" (I think it is ISO 8859-1).
It happens when I use forms to report new bug, to add a note etc.

But when I use the modify button to change a note or bug title or anything else, it keep the right letter.

The DB is all UTF8 and the admin check page indicates that everything is ok with UTF8.

I installed the 2.24.2 and the 2.22.1 versions and created new DB but I still get the same problem.

TagsNo tags attached.

What's funny is that your MantisBT is working well.... I would like the same. ;)

As you have yourself pointed out, UTF8 support is perfectly fine on this bugtracker, as well as on my dev environment. I am able to store and view accented characters without UTF8 <-> ISO-8559-1 conversion issues.

The problem is therefore not caused by a bug in MantisBT, so I will resolve this as "unable to reproduce".

There must be something wrong with your system's configuration. You did not specify what DB engine you're using, but regardless of what the Admin Checks say, I would suggest to double-check if all tables and columns are properly configured to support UTF8.

Thanks so much for answering so quickly!
I use "InnoDB" engine.
" I would suggest to double-check if all tables and columns are properly configured to support UTF8"
I will and let you know if I find something! Thanks!

Note : Here are my system and DB versions :

mysql -V :
mysql Ver 15.1 Distrib 5.5.65-MariaDB, for Linux (x86_64) using readline 5.1
cat /etc/centos-release :
CentOS Linux release 7.8.2003 (Core)

Maybe my problem comes from here (see picture).
All my tables are UTF8 but columns are "utf8_general_ci". It seems different. I'm not a charset db expert, can you tell what you have for your table please?

MariaDB [mantisdb]> SHOW FULL COLUMNS FROM mantis_bugnote_text_table;



ps : Should I alter with "utf8mb4" ?

I checked everything I could think about... No luck...
I made a new fresh install DB. Same problem.
I install a newer mariadb version. Same problem.

Can you let me know what your config system and db is please?
Mine :

mysql -V :
mysql Ver 15.1 Distrib 5.5.65-MariaDB, for Linux (x86_64) using readline 5.1
cat /etc/centos-release :
CentOS Linux release 7.8.2003 (Core)

I uninstalled everything and made a new fresh POSTGRESQL db this time.
Same encoding problem with accents...
I might reset my server to move to Centos 8.

Reseted the server to Centos 8 and no problems with accents anymore.

Thanks but unfortunetly I'm afraid it was for a short time... Last night, when I reported bugs, no accents problems. So I assumed it was thanks to the new install with Centos 8. However, this morning, impossible to report a bug without havind issues accents. See my screen capture it's crazy. Same Mantis, same DB, same computer, came Chrome...
I suspect the problem coming from the time I changed the language from auto (french) to english to french back to auto finaly. But no more luck. I then installed a new version of mantis (same .zip) with a new DB but accents problems still there...
I keep investigating because I really like Mantis. :)

Ok I'm found where the problem comes from.
I realised that I was adding some lines to my php config because I read somewhere I had to do it (I don't remembere where) and these lines cause the problem.

I was adding in php.ini :

mbstring.language = all
mbstring.internal_encoding = UTF-8
mbstring.http_input = auto
mbstring.http_output = UTF-8
mbstring.encoding_translation = On
mbstring.detect_order = UTF-8
mbstring.substitute_character = none;
mbstring.func_overload = 0
mbstring.strict_encoding = Off

After I install new Centos 8 and Mantis, I probably tried to report a bug, saw that I did not have the accent issue anymore then later reboot which activated this config. After that all the new report bugs had accents problems... I removed the lines, reboot (probably a httpd restart would be sufficent) and the problem was gone.

Sorry to have annoyed you with that and thanks for your support.
