Powerline doesn't display correctly on remote Linux sessions

[msg7086]

Hi,

I'm using tmux (byobu) with powerline symbols in the tmux tab bar. Under XShell it looks pretty nice, but with WindTerm it shows ⮀ and ⮁ regardless of fonts I choose. What should I do to correctly display those symbols?

Also they are occupying more than 1 char width, pushing the width of tab bar over the window width, wrapping it to the next line.

Thanks

OS: Windows 10
Font: tested Sarasa Term J, Roboto Mono, Consolas, non worked.

Turns out I'm using the legacy Unicode code point. Switching from U+2B60 to U+E0B0 solves the issue.
