Add Support for Non-Ascii Chars in CiteIds
Add Support for Non-Ascii Chars in CiteIds

For example:
- @alcântara2016

The ‘â’ was breaking the citeid since it wasn’t a unicode character.

To fix
-> Enable /u flag in appropriate Regexes
-> Use \p{L} to match a single code point in the category "letter".
-> Use \p{L} to match any numeric character in any script.

Not 100% on browser support, but I did test in both server and dev versions of RStudio.
