Does the Julia mode support Tab completion for unicode charachers?

Julia supports unicode characters, and some editors support the insertion of such charachters by using the \char + Tab combination. So writing \alpha and then hitting Tab will convert it to α. Does the Julia mode of this plugin (codemirror/mode/julia/julia.js) allow to do that?

The reason I ask is because I want to add that feature to the Zotero notes, which are based on TinyMCE, so I figured if I can add the CodeMirror plugin for TinyMCE, it could work.

Thanks a lot!
