Not musicbee, but maybe it helps... just another approach:
I use
- foobar with foo_discogs for nearly all tags (with a fair bit of fine tuning - only genre & rating is done by semi hand... genre is on discogs, but not too well maintained, and genres mean different things for different people, and I treat keywords as 'genres'/situations...)
- once tagged, there's ascii reformatting within foobar's syntax - which I use for writing file names from tag info [ = $if(%tracknumber%,%tracknumber%-)[$ascii(%artist%-)]$ascii(%title%) - converts everything it can... thai/kytillic/jjapanese are a bit of a problem... combined with foo_discogs defaulting to main artist name with no way out... which if in non-latin letters, I have not found a good solution for... :/, but there is some people on the foobar forums who wrote complete remapping strings [remember seeing russian... not sure about japanese/thai/hebrew/arab/sanskrit/etc...]]
Also, foo_masstagger is neat for mass edits in case need to be shuffled/fixed...
