metaflac --export-tags-to/--import-tags from *may* work, e.g.

metaflac --export-tags-to=tag.from file.flac &&
iconv -f LATIN-1 -t UTF-8 tag.from >tag.to &&
metaflac --remove-all-tags --import-tags-from=tag.to file.flac

(of course test that real well first since it's destructive.  it
also assumes you know the current encoding.  a better script will
also check the iconv result for warnings.)

see
http://flac.sourceforge.net/documentation.html#metaflac_shorthand_import_tags_from

the docs say import doesn't support multiple tags with the same
field name but looking at the code that doesn't appear to be a
problem, but double-check.
