Change Account Name

"Is there a way for GGG to change my account name? Somehow, I managed to insert a strange apostrophe into my name, which makes it impossible for me to use POB. Even though it's my own mistake, I'm still asking.
POB also has a separate page that reformats certain characters, like converting 'í' into íbje#3248, but that doesn't seem to work either..."


This side converts my name https://www.urlencoder.org/

From íbje#3248 to %C3%ADbje%233248
