I'm currently developing a game for Windows systems. The specific details of the game are not terribly important, however the game itself is largely self-contained in a single
.exe file. One thing that is unique about it, though, is that the title of the game contains an accented character: (specifically,
é). This manifests both in the file name of the executable and in the window title of the game at runtime.
For the vast majority of users, there doesn't seem to be an issue. However one user has reported that the program fails to launch when their system locale is set to Japan, but it runs fine when set to an English locale.
I suspect that the accented character in the file name may be the culprit as I feel like I've heard about this issue in similar projects, but it's hard to say. The user in question is not terribly responsive, so I have difficulty in acquiring any more information than this.
My question is, could including this accented character in the game's title be causing compatibility issues with Windows, and what sort of localization issues should I be aware of with regards to file or window name?
