Research direction
Investigate the line wrapping and copy functionality in Termux's terminal view. Likely the issue is in the TextRenderer or the way lines are stored. Check the code for handling double width characters during line breaking. The copy operation may be reconstructing the text with extra spaces due to incorrect width calculation. Look at recent commits or similar issues for context.
