So what exactly is missing from the definition: "any character except <LF>"? Subversion doesn't define the source character set. It does implicitly expect it to be a superset of ASCII, and uses UTF-8 internally. That document intentionally doesn't define what a "character" is except for special codes that the parser recognizes as delimiters, depending on context. -- Brane
