You can use \? to represent "one character" and \?\* to represent "at least one character".

"\?" matches to one of the following types. * 1 ASCII printable character (for 0x21-0x2E or 0x30-0x5B or 0x5D-0x7E) * 2 ASCII printable characters \\ (for 0x5C, which means single "\") * 4 ASCII printable characters \ooo (for 0x01-0x20 or 0x7F-0xFF, where "ooo" is octal value) These 3 types represents one *byte*. I want to say "\? matches to one character", but since expression of a character depends on the value of that byte, I'm saying "\? matches to one *byte* character" instead. Well, this sentence might be confusing, but how can I express more accurately?
