Cooking utensils and Ingredient names cut short with "special" characters

[Yoekkul]

When inserting ingredients/cooking utensils with umlauts or accents they only get partially highlighted. Examples would look like the following:
@ Möre
#Schäler

This could probably be fixed by adjusting the regex in cook.js
For instance the regex used to detect ingredients could be replaced with

if(stream.match(/^@([^@#~]+?(?={))/))
          return "ingredient";
        else if(stream.match(/^@([\p{L}\p{M}]+?\b)+/u))
          return "ingredient";
