Steps to reproduce

  1. Open an Ubuntu 20.04.4 LTS tab inside Windows Terminal.
  2. Execute the following command to generate file "test.txt" which contains the spanish word "automático" using the Unicode "combining acute accent character U+0301" which is represented in UTF8 by bytes 0xCC and 0x81 (hex).
    echo "6175746f6d61cc817469636f0a" | xxd -r -p - >test.txt
  3. Execute the following command to display the contents of the generated "test.txt" file:
    cat test.txt

Expected Behavior

The spanish word "automático" should be displayed inside Windows Terminal without any additional extra spacing between each letter, just like Windows Notepad displays the same file, which is correct:
