Okay, I have converted to foobar recently because of its supposedly flawless support for UTF-8 encoding.
And it did work, until I started tagging Japanese files.

These, of course, are the exact same files. In ID3v1 I've tagged transcriptions of kanji, in ID3v2.4 kanji in UTF-8.
Every other tagging/playback software can read the tags flawlessly, by checking for ID3v2.4 first, and ignoring ID3v1 if v2.4 is present. Not foobar. Instead, it displays a mix of v1 and v2.4, and to be frank, I can't figure out the pattern. When reading this particular album info, it displays album title and some track titles from v1, the rest is from v2.4. With other albums, it displays everything from v2.4, 'cept for a few tracknames. Some albums are displayed 100% correct. In the preferences I have found no option to make foobar read ONLY the ID3v2.4 tags. As well as no option for writing only ID3v2.4 tags without wiping the existent ID3v1, but that's another issue.

Is there a way to solve this problem?
