wordWrapColumn width calculation seems wrong for non-ASCII #94974

Closed deepestblue closed 4 years ago

deepestblue commented 4 years ago

Issue Type: Bug

  1. Set "editor.wordWrap": "wordWrapColumn", "editor.wordWrapColumn": 100,
  2. Set viewPort width to approximately 100
  3. Open long-running English text (e.g. attached English text in the Latin script) as a Plain Text file.
  4. Notice word wraps around the width of the viewport.
  5. Open long-running Tamil text (e.g. attached Tamil text) as "Plain Text" file.
  6. Notice Tamil text is wrapped well before it hits the viewport end (only about 80% the viewport used)

Also repros with Telugu and Devanagari text.

Please use "editor.wrappingStrategy": "advanced".
