Like BUG#2190, when SWAT displays parameter values/share names in VIEW menu, they always display them as unix charset, but should convert them to UTF-8 before generating an HTML pages. P.S. I think that except this and BUG#496, everything around SWAT i18n features now works well.
fixed in 3.0.11
sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
