Not true. If you like, I can send you a copy of the VISCII report showing not only the mappings, but also their justification. The Viet-Std organization went to great lengths to avoid combining characters, even, as John said, to the point of encoding six graphic characters in the C-zero control area. Perhaps you are thinking of Windows code page 1258, which includes many precomposed letters, but none in the Latin Extension B block, and does require combining marks for vowels with two diacritics. -Doug Ewell Fullerton, California http://users.adelphia.net/~dewell/
