[quick edit] quick editor not open when function name has non ascii chars.

[jodyzhang]

1. paste following code in brackets:

function frenchçProp(){
}

put cursor on the function name, press command + E to open quick editor
->it can't open. however if remove char ç, then quick editor shows up.

Expect:
open quick editor on non ascii char as function name

Probably related to #3940. To @dloverin

Look like a code mirror issue with cm.getTokenAt(cursor). The token.string returned is incorrect for non-ascii characters. I'll report the issue.

Was assigned to tern team, so marking "Needs Review".

Note Marijn's comment from the issue open on CodeMirror: this is an issue with how the modes are written and to fix this generically would potentially have memory and performance impacts.

CodeMirror has had a lot of work done over the past 11 months so it's worth checking to see if the behavior has improved, but I'm not hopeful of that given Marijn's comment.
