Glyphs display as a "?" in JetBrains Terminal in macOS Big Sur

[iebb]

Agnoster Theme works normally in macOS Terminal and iTerm 2, but glyphs display as a "?" in JetBrains Terminal.

Interestingly, Oh-My-Zsh works pretty fine in both environments with glyphs displayed correctly, so I guess it's not a powerline issue.

It worked well previously (in macOS 10.15), however when I upgraded macOS to Big Sur today, these glyphs broke suddenly in Jetbrains.

This is related to JetBrains. Please check if your issue is solved in the same manner as https://youtrack.jetbrains.com/issue/IDEA-192522. Otherwise, please check https://youtrack.jetbrains.com/ for a similar issue or open a new one.

After some investigation, I found the problem is related to locale settings.

My current locale setting is en_HK.UTF-8, which is a built-in option for iOS/macOS (English / Hong Kong), however omf seems doesn't support it.

both LC_CTYPE=en_US.UTF-8 and UTF-8 works correctly in fish and zsh, but en_HK.UTF-8 only works in oh-my-zsh.

additionally, other similar locales such as en_IN.UTF-8 and en_MT.UTF-8 doesn't work either.

Seems this issue is the same as #410, however since en_HK.UTF-8 is a completely valid locale - alongside with other valid locales such as en_IN.UTF-8, they should be supported.

This might be an issue with JetBrains, or an issue with Fish Shell itself, but it is unrelated to OMF. You should be able to confirm this by printing a few powerline characters. You'll get the same result with or without OMF installed:

echo \uE0B0 \uE0B1

A good next step might be opening an issue with Fish Shell?

Seems it's an issue with fish shell, since zsh / en_HK works in Jetbrains.
