IIRC for my Yamaha DX7 and the C64 software I've written, it was an issue,  
when naming a sound with a special Japanese ASCII sign. AFAIR it was only  
the combination of one sound + a special name including this sign, not an  
issue when using this sign for other sounds. Voodoo ;). The old (first)  
DX7 itself only provided capital letters, numbers and the dot, perhaps a  
few additional signs, my sound bank manager enabled usage of other ASCII
