Height of terminal changes with split tmux panes

[alanchrt]

I've noticed similar behavior in tty.js

Switching between two tmux windows is fine, and the size of the terminal remains consistent:

However, when I split tmux vertically, the terminal height increases:

It looks like it's one pixel per row. In this instance of 40 rows, it jumped from 600px to 639px in height. It's more pronounced with more rows.

My only guess is that it has something to do with the height of the pipe character – | – being used to split the panes, but I don't know why this doesn't cause issues in split Vim as well.

Any ideas?

Ah, apparently those two characters are slightly different:

>>> ord('|')
124
>>> ord('│')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: ord() expected a character, but string of length 3 found

Still not sure how to resolve it.

This is the offending character: http://www.fileformat.info/info/unicode/char/2502/index.htm

Looks like it depends on the font. Andale Mono does a decent job with it, but has other spacing issues. Any recommended font?

I hit this issue as well in a different context. Any good recommended font?
