Works just fine for me... Have you set the font correct (should be Powerline)

u have tutorial for setup this, mikeerickson?
@mardianto just set Meslo LG L DZ for Powerline in Font Family
Thanks @ttuygun, that solved it for me.
I was trying to use Meslo LG M Regular for Powerline (as in my iTerm2 settings), but that didn't work. Do you have any idea why?
@AlanGabbianelli did you install the font file to the system?
@ttuygun yes, the font is installed.
The problem was the extra Regular that I wrote. I got it working just setting it to Meslo LG M for Powerline, instead of Meslo LG M Regular for Powerline.
I had initially copied it from my iTerm2 setting, but it turns out only the font family is needed, not the font typeface.
Also here is a fix! Install CascadiaPL.ttf from https://github.com/microsoft/cascadia-code/releases it has native Powerline ligatures which your font reported above does not have.
You will also need to setup the terminal to use this CascadiaPL.ttf font, after which the issue should be gone.
However please notice that platformio-ide-terminal may also display other issues with Powerline type input modifiers mostly due to #426 so until there's xterm support nothing will improve in that front.
Any xterm additions are user contributed anyone can contribute via pr to this project or to my fork upstream at https://github.com/bus-stop/terminus which is now completely written in JavaScript.
Hope this helps.
