Is it possible to preserve formatting (specifically colour) of a string when piped through select-string?
I’m using select-string to find entries with specific tags in a git log that’s been pretty-formatted with some nice colours. Unfortunately the colour gets lost in the process, and I get something that looks like non-printing control characters scattered about. This happens even on the “line” property of the match-info object.
I’ve piped the output of the git log into Get-Member and it appears to be a vanilla System.String.
(probably not important, but you can never tell)
The formatted git log command is:
git log --color --graph --pretty=format:'%C(cyan)%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit
I am vaguely aware that I may be able to do something similar with git log switches, and I’m looking into this, but for this question, assume I still need to pipe the output through powershell commands keeping the colours.
Mangled output looks something like this (slightly sanitized). Unfortunately the unicode chars didn’t survive emailing off the system in question.

According to www.babelstone.co.uk/Unicode/whatisit.html there is a control (escape) character in the output with codepoint U+001B, immediately preceding each left square bracket in the previous example, however these were removed by email clients.
