PowerShell Redirection also outputs Terminal Icons code

[RBruce31B]

When Redirecting output with Terminal-Icons enabled, the output also has Terminal-Icons and code within the output.

Expected Behavior

When Terminal-Icons is disabled, code and Icons do not appear in redirected outputs:

Current Behavior

While Terminal-Icons are enabled, redirected output has left over code and if the font is not applied in text editors the icon does not appear:

Possible Solution

I'm wondering if there is a way to disable Terminal-Icons when redirection operators are used? Or a way to parse the code out? Other than that, I have no idea how to fix this.

Steps to Reproduce (for bugs)

1. Import-Module Terminal-Icons
2. gci | select -First 5 >> filename.txt (Tee, ">" and Out-File also output same thing) (Export-CSV does not display Terminal-Icons which is what I am looking for when redirecting output.)
3. ". filename.txt"

Context

I work a lot with CSVs and redirect data a lot using PowerShell. Finding a fix or workaround will make my life easier while still having a cool prompt!

Your Environment

• Module version used: Latest
• Operating System and PowerShell version: Windows 11 Pro and Windows 10 Pro PowerShell Versions: PowerShell 5.1.22000.282 PowerShell 7.2.1

Same Behavior in Windows Terminal version 1.11.3471.0

@RBruce31B As a workaround, you can do something like this:

Set-TerminalIconsTheme -DisableColorTheme -DisableIconTheme
gci | select -First 5 >> filename.txt
Set-TerminalIconsTheme -IconTheme devblackops -ColorTheme devblackops

Not sure if this will help the developers, but maybe conditionally rendering the ANSI sequences and/or the icons depending on the value of $PSStyle.OutputRendering could be something to consider.

I'm having the same issue using powershell as my shell in neovim. Anything shown in the builtin pager will display any ansi sequences that are there. Using the -DisableColorTheme and/or -DisableIconTheme flags actually makes it so much worse, because it just wraps everything in ansi ( ^[[0m )

:!Set-TerminalIconsTheme -DisableIconTheme -DisableColortheme ; ls
