Custom charset with mask files

[swing]

Hi,

How do I provide my custom charsets when using mask file?

For example, I'm able to crack my UTF-8 password this way:

Code:

hashcat64.exe -m 0 md5.txt -w 3 -O -a 3 -1 charsets\my1.hcchr -2 charsets\my2.hcchr -3 ?l ?1?2?1?2?3?3?3

But how do I put such mask into a mask file?
When I try:

Code:

hashcat64.exe -m 0 md5.txt -w 3 -O -a 3 -1 charsets\my1.hcchr -2 charsets\my2.hcchr -3 ?l test.hcmask

and put into test.hcmask

Code:

?1?2?1?2?3?3?3

I get error: Custom-charset 1 is undefined

If I try to put my custom charsets into mask file, like this:

Code:

charsets\my1.hcchr,charsets\my2.hcchr,?l,?1?2?1?2?3?3?3

And run like this:

Code:

hashcat64.exe -m 0 md5.txt -w 3 -O -a 3 test.hcmask

Then password is not found

Can you please suggest how to pass custom charset into a mask file
Thanks!
