Java allows all unicode-letters in variable names, not only latin letters. Is there a chance to include these characters in the identifier regex?

Otherwise, this is how valid java code would look like:

My current approach is to copy-paste the grammar and change it from

github.com/lezer-parser/java@14901c5f4a/src/java.grammar (L712-L714)

  identifier { $[a-z_$äöü] $[a-zA-Z0-9_$äöüÄÖÜß]* }

  capitalIdentifier { $[A-ZÄÖÜ] $[a-zA-Z0-9_$äöüÄÖÜß]* }
