Charset files don't behave as expected?

[bbcjared]

So when searching for 6 character password in Cyrillic using mask, I'd have to double that and now I'm searching for 12 character password?!? i.e. ?1?1?1?1?1?1?1?1?1?1?1?1

Then we have Chinese and Korean character sets that are 3 bytes long in UTF - E384B1 now Korean 6 symbol password becomes ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1 (18 character long) even though I'm looking for combination of 6 symbols from a charset.
