[BUG] Broken committer name matching when it contains non-letter chars

[webknjaz]

Hi, the website is able to find my commits by email @ https://openhub.net/committers?query=webknjaz%40redhat.com&find_by=email (and using other emails).
It shows commits with different ways the name ended up being included. Some include parentheses and emojis.
I'm able to claim commits with ASCII-only spelling. When I attempt claiming the rest, each time, it errors out with Committer name No recognized committer with that name.
The error string seems to be coming from

ohloh-ui/config/locales/positions.en.yml

Line 88 in 0a53bf9

no_name_fact: No recognized committer with that name.

.
So I imagine there's inaccurate normalization/comparison somewhere in the claim flow that doesn't fail when scanning repositories or storing them to the DB. It only crashes on claim attempts, AFAICS.
