Tmux vertical boundaries break only when using iTerm

Question

On my new assignment, I will need to use mac, and I'm trying to use tmux with iTerm version 2.

While horizontal borders are displayed with the corresponding ACS field drawing characters [1], vertical borders are interrupted. This is not a problem in Terminal.app, borders are displayed correctly. The problem occurs regardless of the font selected.

In all the screenshots I can find iTerm and tmux, this seems to be the case. Is this just a limitation of iTerm, or is there a problem with my terminfo or locale?

[1] Are Tmux boundaries displayed as xq instead of strings?

Answer 1

The gap you see between the characters of the vertical line is a combined effect of the current font design and vertical spacing. For me, I saw a noticeable decrease in spaces when I switched to Courier New, but I also do not see the difference between iTerm2 and Terminal for the same font. Decreasing the vertical distance from the font selector can help, but it can also interpret lines too much.

Answer 2

Old post, but in any case for people who look at it still. My best bet is to set a different font for Non-Ascii characters and my actual font used for ASCII characters.

For reference, I use Menlo for Powerline for non-ASCII and Droid Sans Mono for my ASCII font, and this sorts the vertical spacing between lines without waving the vertical spacing, etc.

Update: it worked for me! https://github.com/Determinant/inconsolata_for_powerline_mod

I do not think this is a solution. I noticed the same problem. I see that if I make my font huge, the alphanumeric scale will be appropriate, but there will be no window drawing symbols. I don’t know where the problem is. Pay attention to the attached image, as the alphanumeric sizes are scaled proportionally, but the line drawing characters do not have. Inconsolata font at 14pt.

In iTerm2, I managed to get things that look almost perfect using a larger font for characters other than ascii:
