Ignoring folders with certain UTF-8 characters present

[PhilC58]

One Tagger is awesome except for problems I am having reading from certain folders in my library that use UTF-8 characters for organizational purposes, e,g: Ω-FB2K Library and §CLEANED, These are valid Windows folder names that are recognized and handled by numerous other applications including Foobar2K, Rekordbox and EngineDJ, so it is quite frustrating that One Tagger simply ignores these folders, saying: "NO FOLDER SELECTED" when one of them actually IS selected. Reorganizing my library at this point would ruin my libraries, but I would dearly love to add additional metadata to my tracks. Is this a bug, or can such characters not be supported at all?
