Show Content sur test00..2_Sig1.txt show good characters.
But not MS-Outlook ;-)

Mantis Product version = 1.1.2

test0000002_Sig1.txt looks fine when I open it in my text editor. What does it look like for you?

Sorry, i was absent. For me too, the upload file " test0000002_Sig1.txt" is ok with an editor.

Emails with MS-Outlook :

1) Emails sent by "Send a reminder" (=Envoyer un rappel) are good, even with special characters (à é è ç ÿ ...).

2) Automatics emails send for a change have not good display for special characters (see new upload file "BadDisplay.jpg" : "The following issue has been UPDATED."="Le bogue suivant a été mis à jour").
To have a good display, you have to change the coding of the email to UTF-8:
"Affichage || Codage -> || Unicode (UTF-8)" (Affichage=Display, Codage=Coding).

In Mantis web display :

It is ok everywhere except in "Summary" tab (Synthèse) with jpgrap. In upload file "GraphiqueDeSyntheseParSeverite.jpg", "sévérité", "fonctionnalité" and "cosmétique" words bad.

Please update to Mantis 1.2.x with a Unicode database and UI. Things should be OK after that. Please provide feedback.

I cannot upgrade to Mantis 1.2 because it is a development version and i have not the good level for PHP (5.2.0 minimum for Mantis 1.2, i have 5.1.6).

On my database (default creation):
"
mysql> show create database test;

show create database test

When i update to Mantis 1.2, i will try and complete this bug.

We have Mantis 1.1.6 with UTF-8 MySQL database.

And now, automatic emails are OK.

But the problem is the same with
"Synthesis graphs by severity"
