This is a very old SONY problem with non-ASCII characters
ClickCure does not work also, if a target name has at least one non-ASCII character.
All settings of variables with non-ASCII characters does not works (Making unusable lot of features in great Fetish market window -- even simple OnHover of Find button corrupts everything)
And even more, if you just select some non-ASCII characters and make Ctrl-C / Ctrl-V you will see some strange symbols instead.
So this looks like it is just bad non-ASCII characters implementation by SONY. This bugs here for at least two years, so I think they just do not fix it.
So, most useful features of Fetish is unavailable on localized servers
