Well, post the command you are using..
Just tried that out for sh1ts and giggles, and yes, it does work.
I edited the charset.lst file by including your proposed mangled list and running as usual it works OK (and doesn't include the zeroes)
Added the proposed charset in charset.lst as follows ;
Then checked output with;
lalpha-numeric-mangled = [qwertyuiopasdfghjklzxcvbnm768932541]
An interesting test, but not really going to break any boundries with it me thinks.
./crunch 8 8 -f charset.lst lalpha-numeric-mangled
