Ok, I think I am lacking context here. I will have a look at the actual
source you were referring sometime during the coming day or two.
Just one clarification. The very fact that the same person who is doing
the BiDi support also happens to have experience with MBCS does not mean
the two are in any way related. One is centered around west Asia and
north Africa (a.k.a. - the middle east), while the other is at east Asia
(a.k.a - the far east).
I don't mind receiving ownership over all non-western languages, as I
speak a BiDi language, and have experience in programming for an MBCS
language (and between the two you are almost cover the entire range of
problematic languages), but that does not mean that the two are, in any
BTW, bringing us to the "ownership" issue. Is wine going to have a
"Credits" file, sorted by lines of code submitted or similar criteria?
It would be nice to have my name there in case I am ever fired for
answering WINE emails while at work ;-).

Like I said before - I'll have a look at the actual context and voice my
