Char literal syntax highlighting wrong for double-quote '"'

[wyckster]

Issue Type: Bug

The Kotlin syntax for a double-quote char literal is '"'. Enter this by typing '"'. This syntax is highlighted incorrectly in vscode. It's highlighted as if the double-quotes somehow trump the single-quote char literals, which they should not.

Here is some Kotlin source code that illustrates the problem.

val a = '"'
val dummy1 = 1
val b = '"'
val dummy2 = 2

Here is an image showing the incorrect syntax highlighting in vscode:

Compare to an image of some correct highlighting from Android Studio:
