Problems with non-English hashes

[vladimir125]

You're probably using the wrong charset.

That's possible, any suggestions on how could I find the error?

Encoding matters.

Does it matter even if I'm using an HEX charset and a masked attacked?
Can you please just point me in the right direction, at least to narrow down the source of the problems? Should I take care of the encoding even of the charset file, even if I'm using them as HEX?
Moreover, since it's my first time using them, did I converted it right? ie a single string with all the consecutive chars?
