Problem rendering unicode (and emojis) in UCM #4200

Open gerardbosch opened 1 year ago

gerardbosch commented 1 year ago

UCM version: ucm version: release/M5b (built on 2023-07-13) OS: Ubuntu 23.04 Shell: Zsh Terminal: gnome-terminal or Kitty Unison installation: Nix flakes

The issue has been discussed and tested a little on Slack, this is the reference: https://unisonlanguage.slack.com/archives/CLUNF0J5S/p1689285260929389

It happens on Linux, both Zsh and Bash. 2 terminals has been tried with same result: gnome-terminal and Kitty.

(See the Slack thread for details and more screenshots)

This is the output of locale and infocmp commands:

👇 Setting (exporting) the empty ones (LANGUAGE and LC_ALL) to en_US.UTF-8 did not fix it.

locale:

``` LANG=en_US.UTF-8 LANGUAGE= LC_CTYPE="en_US.UTF-8" LC_NUMERIC=es_ES.UTF-8 LC_TIME=es_ES.UTF-8 LC_COLLATE="en_US.UTF-8" LC_MONETARY=es_ES.UTF-8 LC_MESSAGES="en_US.UTF-8" LC_PAPER=es_ES.UTF-8 LC_NAME=es_ES.UTF-8 LC_ADDRESS=es_ES.UTF-8 LC_TELEPHONE=es_ES.UTF-8 LC_MEASUREMENT=es_ES.UTF-8 LC_IDENTIFICATION=es_ES.UTF-8 LC_ALL= ```

👇 I see some reference to linuxbrew in the following output. I installed Unison using Nix flakes, just in case there could be a weird incompatibility in something...

infocmp:

This screenshot could help further investigate or give some hints.

It seems that in case of errors, UCM correctly renders unicode. So I guess there is something done differently when rendering characters on the upgrade (initial screenshot) and the error flows than in the command line input (and welcome) flows.

I see this issue on macos as well.
