Detailed Description

A holder for a string, which stores the length and caches the hash value. A UT_StringRef does not necessarily own the string, and it is therefore not safe to e.g. store a UT_StringRef in a container or member variable.

If the string is already valid, the string itself is returned. Note that this does NOT force the name to be non-zero in length. The safechars parameter is a string containing extra characters that should be considered safe. These characters are not converted to underscores.
