You are actually mistaking two different things here.
CJK languages such as Japanese can be represented by either Unicode or a
double byte value using a particular code page. The first value is
specifically not an "ASCII" value since a DBCS lead byte will not be in the
first 127 characters.
But Devanagari can only be represented by Unicode, thus you must send a
single Unicode code point in a PostMessageW function, and there is no
non-Unicode method you can use.
In any case, if you are using VB <= 6.0, you cannot have it represent a
"Unicode only" script such as Devanagari; you cannot even represent Japanese
if you are not on a system that has a Japanese default code page -- although
you can temporarily "fool" VB by sending messages, the data can be very
quickly corrupted since VB will convert data yo the default system code
page, which will convert both of these things to '?' very quickly.

No, there is not -- but this is not really something you need to do here?
Just use Unicode code points and PostMessageW and then you do not ned to

Not sure what you are looking for here from a control or dll to do.
