That does make sense I had a derp moment, I am just glad your on top of bugs... I played with a really old version way back when so I do know what your talking about.
If you create a character name with 10 characters upon logging out and back in again your name becomes "---" and at the character selection screen some random symbol is shown after the name you picked ...
for example using: "TEST123456" will be "TEST123456Ôö¼├ë├ö├ç├│" at the selection screen...
