Unicode username with Σ as the final char leads to an error loading profile page

[Falco]

@chrispanag

The username is ΣΠΥΡΟΣ (which is the capital form of σπυρος)

Hmmm.

If I try to load the upper case it loads: Προφίλ - ΣΠΥΡΟΣ - Ρεμπέτικο Φόρουμ at first and then fails on a subsequent JSON fetch to the lowercase version.

Looks like an error between our upper/lower case handling.
