One line summary of your issue
[3.2.X] Illegal Character "œ" in "\common\dynasties\00_dynasties.txt"

Game Version
3.2.2

What expansions do you have installed?
All of the above

Do you have mods enabled?
No

Please explain your issue is in as much detail as possible.
"œ" was omitted from ISO-8859-1(it was defined in ISO 8859-15)
And I guess ISO-8859-1 is native encoding being used for CK2.
However there is duke of Mumu, house "Mœscraige", Ireland, 936 bookmark in game.
It does not break the gameplay but it breaks the game save only if the player want to quick save the game.
See error.log for more detail,

[virtualfilesystem.cpp:728]: Could not open file: save games/Mݳcraige/936_08_07.ck2, error: filename is illegal or insecure
[eu3idler.cpp:12473]: Failed to write save file File exception: Exception in: D:\jenkins\workspace\ck2-steam\clausewitz\pdx_core\virtualfilesystem.cpp, line: 730. Description: Could not open file: save games/Mݳcraige/936_08_07.ck2, error: filename is illegal or insecure

Edit:
I attached the origin log file, in order to avoid encoding changes in the copy&paste process.
I'm running CK2 on Windows 10 (1903). My system locale is English (United States)

Steps to reproduce the issue.
1.Start as duke of Mumu, Ireland, 936 "Iron Century"
2.esc>quicksave. But the game is not saved. No warning, no errors popup.

No, as far as i know and is and was commonly known it's Windows-1252.

Apart from that i tested this and can also not create a save file with Quicksave
and get the same error messages in the error.log.

Autosave still works, but i wonder if this related to sometimes ironman saves becoming corrupted/ non-achievement files.

No, as far as i know and is and was commonly known it's Windows-1252.

I used to think so until this bug happened.
It seems CK2 supports Windows-1252 to some extent, like UI/fonts. But when it comes to core stuff like virtualfilesystem, it fallbacks to ISO-8859-1.
That's the reason I say "ISO-8859-1 is native encoding"
