In every case: turn on "Draw intense colors in bold font" in Edit
Profile → Appearance.
The feature:
* Use some font which has "Bold" style available and set it to "Regular"
style.
* Run: `printf '\033[1mBold|\033[0m|Normal\n'`
* "Bold|" text should use bold font.
Different weights:
* Use some font which has multiple weights available (e.g. Thin, Bold,
Heavy, ...), e.g. Source Code Pro.
* Select lightest style.
* Run: `printf '\033[1mBold|\033[0m|Normal\n'`
* Select "regular" font style.
* Bold text for "regular" style should be bolder than the text for
lightest style should be.
