Ok, so we need this code or somethign very similar to support mixed case filesystems.

Yes, I know what the code did - it allowed us to support mixed case ascii-ci filesystems. All you've said is "if we remove mixed case support the code is cleaner" but not addressed the issue at hand. I'll try asking the same question a different way: if we keep this code, will it work for mixed case unicode filesystem or do we have to re-implement mixed case matching differently?
