##### Piping non-ASCII content to ripgrep
When piping input into native executables in PowerShell, the encoding of the
input is controlled by the `$OutputEncoding` variable. By default, this is set
to US-ASCII, and any characters in the pipeline that don't have encodings in
US-ASCII are converted to `?` (question mark) characters.
To change this setting, set `$OutputEncoding` to a different encoding, as
represented by a .NET encoding object. Some common examples are below. The
value of this variable is reset when PowerShell restarts, so to make this
change take effect every time PowerShell is started add a line setting the
variable into your PowerShell profile.
Example `$OutputEncoding` settings:
* UTF-8 without BOM: `$OutputEncoding = [System.Text.UTF8Encoding]::new()`
* The console's output encoding:
`$OutputEncoding = [System.Console]::OutputEncoding`
If you continue to have encoding problems, you can also force the encoding
that the console will use for printing to UTF-8 with
`[System.Console]::OutputEncoding = [System.Text.Encoding]::UTF8`. This
will also reset when PowerShell is restarted, so you can add that line
to your profile as well if you want to make the setting permanent.
### Known issues
#### I just hit Ctrl+C in the middle of ripgrep's output and now my terminal's foreground color is wrong!
Type in `color` on Windows and `echo -ne "\033[0m"` on Unix to restore your
original foreground color.
Type in `color` in cmd.exe (Command Prompt) and `echo -ne "\033[0m"` on Unix
to restore your original foreground color.
In PowerShell, you can add the following code to your profile which will
restore the original foreground color when `Reset-ForegroundColor` is called.
Including the `Set-Alias` line will allow you to call it with simply `color`.
```powershell
$OrigFgColor = $Host.UI.RawUI.ForegroundColor
function Reset-ForegroundColor {
$Host.UI.RawUI.ForegroundColor = $OrigFgColor
}
Set-Alias -Name color -Value Reset-ForegroundColor
```
