Description

Some unicode characters don't show up when launching this terminal on macos, but work when connected via tmux on other session

Environment

• Contour Version or Git commit hash: 0.2.0 1332(prerelease)
• Operating System (name / distribution / version): macOS 11.3.1
• Contour configuration: can reproduce with stock config
• TERM environment variable: xterm-256color
• Compiler version: didn't compile from source

Steps to Reproduce

Open the terminal. Here a detailed video

Expected behavior (frame excerpt from the video):

@mTvare6 I just merged some font fallback related changes (and more) to master. So it might be interesting to know if that fixed it. I sadly quite much doubt that and instead think that your problem might be related to your locale settings.

Would you mind giving that a try? Check the output of locale and echo $LANG`output and see if they differ when being in contour + no tmux and contour + inside tmux?

Mind, Contour currently only supports UTF-8, none of the other legacy encodings, such as iso-8859-15 etc. I also don't think it's actually worth implementing on new terminal implementations. I'm not hard-coded on that way of thinking. Maybe some other users/devs have an interesting insight on that point of view. ;)

@christianparpart default locale for macOS is C and LANG is unset:

~ via ⬢ v14.16.0 via 🐘 v7.3.24 via 𝗥 v1.52.1
➜ locale
LANG=""
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

@mTvare6

Try that one: https://github.com/contour-terminal/contour/releases/tag/v0.2.0.171_rc2

And if you don't mind, please send me the locale output from outside and inside tmux, just like @uspasojevic96 did (I try to repro that though, too).

In tmux, opened with contour

LANG=""
LC_COLLATE="C"
LC_CTYPE="C"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

In tmux, open with iTerm2

LANG=""
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

So from seeing this, I think LC_CTYPE is set to something wrong?

I am closing this issue, because I seem not to be able to get to reproduce it. It also is very long ago and we had no similar reports.

@mTvare6 if you happen to still see them, please reopen this issue and we then will probably need more input with a fresh look on it.
