Allow characters in various representations to be parsed to reverse lookup

[davelab6]

$ pyfontaine 0x011F works, but other representations don't, which means the chars have to be converted by another tool, which sucks :)

• [x] $ pyfontaine U+011F works
• [x] $ pyfontaine ğ works

I think the 'True' col can be removed, its 'unix like' to just print the cases where it is found.

$ pyfontaine ğ ;

Ah this True col is because of multiple input.
