Mentions are not matching unicode/diacritic characters

[Adrienb91]

Type of report

Bug

Provide detailed reproduction steps (if any)

1. Use CKEDITOR 4.10 with mentions plugin
2. Include mentions data with accents like 'Céline TEST'
3. Try to use mentions with data typing '@Cé'

Expected result

Mentions propose entry 'Céline TEST'

Actual result

No results

Other details

It seems due to emphasis/accents
I've tried with direct data in array or with function feed.

I think we would have same results trying with accents or not (@cel or @Cél must return same results).
It can be solved with a new regexp parameter to apply to request and data ?

Thanks per advance !

• Browser: Any
• CKEditor version: 4.10
• Installed CKEditor plugins: Mentions

I can confirm the issue. Looks like it happens with pretty much any unicode characters, I was able to reproduce the problem with some Polish characters too.

I have prepared a codepen demo that I'll put in repro steps above.

@Adrienb91 I had a quick look at this and I was able to come with a workaround to this problem, you can temporarily apply it yourself before we come with a upstream fix, it's enough to adjust CKEDITOR.plugins.mentions.configDefinition.pattern property, like so:

mentions: [ {
	feed: ['Anna', 'Anęmość', 'Thomas', 'John'],
	minChars: 0,
	pattern: /\@[a-zA-Z0-9_À-ž]*$/
} ]

That should cover you with diacritics you're looking for. Here's an example (it uses Polish diacritics but feel free to adjust the config to include any other entries): https://codepen.io/mlewand/pen/PyRQOE

It does not cover all utf8 chars, but it can be extended in case of need.

@mlewand : Thanks a lot, it works like a charm !

I've added spaces and & character : pattern: /\@[a-zA-Z0-9_\s&À-ž]*$/

@Adrienb91 I'm glad it has worked for you. Meanwhile I'm leaving the issue open, as it is valid and the default matching should be changed to also include mentioned diacritics characters.

Until it gets patched the easiest way is to adjust the pattern in the configuration.
