samba - Jan 2011 - mapping chars for non-DOS names under UNIX

Hi All,

As known, samba can mapping non-DOS names under UNIX   to DOS-compatible
names by using some HASH/HASH2 algorithm. but is there some ways we can
define a character mapping tables by self? such as: just a sample
" <-------> a
* <-------> b
/ <-------> c
: <-------> d
< <-------> e
> <-------> f
? <-------> g
\ <-------> h
| <-------> i

Thanks and Regards.
