Extra space in pwsh when using surrogate pair with oh-my-posh

[sharky98]

Describe the problem:

When I use a surrogate pair (such as \udb80\udced for the nf-md-calendar icon), there is an extra space before the trailing diamond and after the content of the segment that does not get styled.

The weird thing with Tabby is that it happens only with pwsh, while other terminal have same behavior between pwsh and bash through SSH. I suspect you may not be using the same rendering dependency for both?

• Tabby
  • ❌ pwsh.exe: omp.pwsh.tabby.log
    
  • ✅ bash through SSH: omp.bash.tabby.log
    

To Reproduce:

Tabby Version: 1.0.215

Use a surrogate pair in any segment such as below.

{
  "blocks": [
      "segments": [
        {
          "background": "#234d70",
          "foreground": "#d6deeb",
          "leading_diamond": "<transparent,background>\ue0b0</>",
          "properties": {
            "time_format": "2006-01-02"
          },
          "style": "diamond",
          "template": " \udb80\udced {{ .CurrentDate | date .Format }} ",
          "trailing_diamond": "<background,transparent>\ue0b0</>",
          "type": "time"
        },
    ]
  ]
}
