Unicode characters in CSS properties

[valtlai]

Highlight Unicode characters in CSS properties correctly, for example .foo { --bär: 3 }.

Optimized the “function” regex in the JavaScript definition: replaced _a-zA-Z0-9 with \w, removed uppercase A-Z because the i flag is set.

Used that regex for CSS but removed $ and added -.

Hi! Thanks for contributing. Could you run gulp to generate the minified versions (and the prism.js file) please?

Also, can you update the test file for CSS properties with an example using unicode characters, and make sure it passes? You can use npm test to run the tests.

Do I need to install Gulp and NPM, eh?

[valtlai]

Added a test (and fixed indentation).

Yes, indeed.

[valtlai]

I have not use them ever. When I have installed both do I just cd to the local directory and run the commands?

[Golmote]

You need to cd to the local directory and run npm install.
Once it's done, you should be able to run gulp and npm test.

[valtlai]

Added minified versions, and tests passed.

Awesome thanks! Can you add the prism.js file to the PR? It should have been modified when you ran gulp.

[Golmote]

Great! Looks good to me. Thanks again for contributing!
