Thanks. Can you show a before and after picture? Also, did you first try heavy character bar ┃ (or maybe you are going lighter)?

I'd prefer letting the indent-bars-no-stipple-char-font-weight default be nil, then incorporating in the font specification only if the parameter is non-nil, ala:

,@(when indent-bars-no-stipple-char-font-weight `(:weight ,indent-bars-no-stipple-char-font-weight))

I've tried with the heavy character bar ┃ and it can achieve the same effect by customizing the font weight.

I think it's OK. However, nil is not a valid value for the font weight attribute and this maybe a misleading.

Thanks, that looks great. We can simply document the custom variable like: "If non-nil, set the no-stipple character font weight accordingly." or similar.
