Use of .hcchr files

[mastercracker]

Hi. I wanted to try using the new charset in file feature but while doing some testing I got some crashes. There could be many reasons for it and I don't have the time right now to track the source. My real question is: is it possible to combine 2 charsets together. With predefined one it's straightforward:

Code:

-1 ?s?l

But let's say that I want the russian characters with numbers. What is the right method?

This:

Code:

-1 charsets\standard\russian\ru_cp1251.hcchr?d

or

Code:

-1 charsets\standard\russian\ru_cp1251.hcchr -2 ?1?d

or

Code:

-1 "charsets\standard\russian\ru_cp1251.hcchr ?d"

?

P.S. I don't want to open and modify the .hccr files because I am afraid to mess them up.
