7F is a legal XML 1.0 character and XML 1.0 should accept it. And, yes, I believe that in UTF8 (are you SURE you're reading the file as UTF8 rather than some other encoding?) it should be a legitimate single byte.
However, the XML 1.0 spec's section 2.2 says "Document authors are encouraged to avoid "compatibility characters", as defined in section 6.8 of [Unicode] (see also D21 in section 3.6 of [Unicode3])." So using this character is ill-advised, even though it is legal. XML 1.1 does generally accept more characters than XML 1.0 does -- but note that 7F is one of the RestrictedChars, and that XML 1.1 explicitly says these may not appear within documents or external parsed entities. (Alas, the Recommendation does not explain why these are restricted.) Looks to me like you have several choices: Eliminate that character, encode it somehow (note that a numeric character reference probably wouldn't solve this problem), or go back to XML 1.0. ______________________________________ "...
