[otrs] Japanese language Encoding

Dear Murahashi San, I have been checking as you already know the japanese encoding system in OTRS. I already got good advances using perl filtering with dot-qmail file converting the characters to Shift_JIS. It has been working very well with the exception of the hiragana letter "RA"(ら) and once in while when replying to a customer, all the message enconding is being broken. It would be very helpful if we share our advances to help each other in some direction to solve this problem making the results public as a great benefit to all OTRS users. Thanks in advance, Isamar Maia Oaklawn Marketing
