Here’s terminal’s interaction settings

Steps to reproduce

This seems to only be an issue in TMUX… however I’ve tested this in the current stable terminal version of 1.16.10261.0 and it is not a problem

try to copy the text sl iam token refresh. You have to be careful not to get any pre or post characters.

• as far as I can tell, the terminal colouring has no effect on this

empty clipboard

selecting text to copy

Japanese text copied to clipboard

selecting text to copy - with additional text at beginning

proper text copied to clipboard

Expected Behavior

copy text sl iam token refresh into clipboard

Actual Behavior

copies out text 汳椠浡琠歯湥爠晥敲桳 which when pasted into google translate, is apparently Japanese for toothpaste
