Multibyte special character messes up initials

[rvanlaak]

We parsed the author name from a page, where the input name is © Pavel Voinau.

Expected result

not return an initials, return null as initials

Actual result

When dumping the value, name-parser exports "Â ©"

How to fix

• make initial parser multibyte safe
• do not parse copyright sign
