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

Type: Bug

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.

VS Code
- ❌ pwsh.exe: omp.pwsh.vscode.log
- ❌ bash through SSH (in pwsh.exe): omp.bash.vscode.log

See https://github.com/JanDeDobbeleer/oh-my-posh/issues/5706 for original report.

To Reproduce:

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"
        },
    ]
  ]
}
