Description

[Jiri Motycka]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; cs-CZ; rv:1.8.0.12) Gecko/20070718 Fedora/1.5.0.12-4.fc6 Firefox/1.5.0.12
Build Identifier: Thunderbird 2.0.0.9 + Lightning 0.7

When email invitation comes to a mailbox and user displays it, so if invitation contains special characters with diacritics (code page of invitation is UTF-8), this invitaion is specialy formated to message view pane and this special characters are not displayed correctly (default char. set for incomming and outgoing emails iso-8859-2). When i try to accept this invitation through special accept button, it is imported to callendar with wrong characters too.
I try to change codepage at main menu to different one (UTF-8 is autodetected) and then back to autodetected UTF-8, the message becomes correctly displayed and acceptation to personal callendar start works too with correct imported text.
It is possible that for other codepages it will not works too.

Reproducible: Always

Steps to Reproduce:
1. show message with invitation to an event (def. charset iso-8859-2, invitation mail with special national characters in UTF-8)
2. accept mail to a personal callendar -> same wrong displayed characters will be in event in callendar
3. switch to different codepage through main menu
4. switch back to the original autodetected codepage
5. now the invitaion mail will be diaplyed correctly
