is it normal that walkman and system doesn't support same language?

I flashed my W580i with
W580_R8BA024_FS_TAIWAN_RED52
W580_R8BA024_MAIN_TAIWAN_LA_RED52
W580i_CDA102774_6_R2A_Customized_Taiwan

so that I can display Japanese characters on my phone.
Everything was fine, but I find it weird weird that the file manager of the phone is able to display Japanese characters and Unicode characters correctly, while Walkman display "????"question marks for all Japanese characters and "square" for all Unicode symbols such as 「☆」 and 「♥」

Is this normal? Or does this mean that flash failed?

i flashed TAIWAN version because it supports Japanese display. but now only the file manager can display Japanese characters, the walkman just gives "???" and squares

problem solved....
I just realized that id3v1 tag doesn't support Unicode, no wonder....
Originally I wrote both id3v1 and id3v2 tags, but it seems that walkman stops when it found id3v1. Now that I deleted id3v1 tags, walkman display all characters without any problem
