By "UNICODE" I assume you mean UTF-16, which is one encoding form of Unicode (as is UTF-8). By "control character[s] or escape sequences" I assume you mean characters below 0x20 in ASCII, or below U+0020 in Unicode (any encoding form). (That is, I assume we are not talking about the so-called C1 control characters from U+0080 to U+009F.) A UTF-8 string will contain control characters if and only if the corresponding UTF-16 string contains characters in the control range (below U+0020). For strings that consist entirely of ASCII characters, the UTF-8 representation is identical to the ASCII representation. For the specification of UTF-8, including some examples that should help answer your questions, see http://www.unicode.org/versions/Unicode4.0.0/ch03.pdf (pp. 24-25). -Doug Ewell Fullerton, California http://users.adelphia.net/~dewell/
