Tell me how you did "locale change".
So you are literally in Japanese locale (as seen in
post #156) (after restart, of course), OR using the latest Locale Emulator and emulating Japanese Locale (right-click the game.exe -> Locale Emulator -> Run in Japanese), and the text cutting off still happens (see post #155 for comparison)?
Well, try what changeling suggested a couple of posts above and put the game into an "easy" folder, that is something that doesn't have ANY special characters (also take care that your "user" folder might contain those too!!), like d:\games\Trixxx\Otome, and make sure that the VLGothic font that comes with the game (in the game folder's Fonts directory -> VLGothic-Regular.ttf is placed in your Windows\Fonts (and installed?), just to be on the safe side.
Nothing else makes sense why it wouldn't\couldn't work. To me, at least. lol
