No, definitely not isolated to Fedora. It's any distro, or any that are set up, in a way that PS doesn't like in terms of the xterm environmental. So most, I would assume, are affected, but all have a fix. It's a PS bug, and decently easy to work around.
Right click and choose preferences.
Switch to the Input Method tab and click Add.
Select the language you want to add.
Select the input type for the language. In this case we want Anthy in order to get the Romaji entry of the Kana.
As a side note, my wife does not use the Kana Kanji input method. I am not sure how many Japanese actually use that input method. The one time I put my laptop into that mode, she could not type.
After adding Anthy, you can click prefernces and make any custom changes you want.
As someone upvoted this post recently, I thought I would circle back. I am using simlinks in all my Fedora systems now.
This just never worked exactly as advertised. It mostly worked, but never completely.
I also use symbolic link with Linux and Windows too. For Windows, it keeps me from messing with the default user shell folders / shell folders path or the need to move the locations. And with Linux, I don't have to mess with the user-dirs.dirs file.
