I have downlaoded 2.9.3.1431 beta (May 8th 2008): and I have found Bosanski language but some letters are not shown correctly.
Only English letters are correct.
Installation doesn't show ani of the following letters: Č, Ć, Đ, Š, Ž
I have saved my translation in unicode format, but inside installation it doesn't look right.
Here is the list of incorrect letters:
Shown Shoud be
җ --------ć
Љ -------š
и --------č
р --------đ (but not all)
ћ --------ž
It seems to me that you have chosen cyrilic encoding for Bosanski instead of central European
In attachment you can find image vith some errors highlighted.
