ANSI color in git is not displayed correctly

Question

Recently, I switched to SLES 11. I found a problem for git command. All the ANSI color could not be rendered. Instead, it shows the ANSI code like this:

*ESC

Answer 1

Whoever ever winds up here, in my case it was solved by setting core.pager to an empty string, instead of unsetting it:

git config --global core.pager ''
