Hi,

Q: Is lower-case UUID a problem?

A: No. A UUID is a 128-bit value, and what you see is just the hexadecimal representation of that 128-bit value. It’s not text (string/character), i.e. its not case sensitive.

Actually, the latest international spec states:

6.5.4 Software generating the hexadecimal representation of a UUID shall not use upper caseletters. NOTE – It is recommended that the hexadecimal representation used in all human-readable formats be restricted to lower-case letters. Software processing this representation is, however, required to accept both upper and lower case letters as specified in 6.5.2.
