Thank you for reporting this! This is the same issue as #728. Those characters are called "ANSI escape codes". They let you specify that text should be rendered in a different colour. However, we should only be using them when the output is going to a TTY (such as a terminal). When a tool is using the output, we should not render them (unless you force it with --color or something similar).

In your TeamCity issue, you should mention that TeamCity should support ANSI escape codes :)

I'm going to close this out. Please follow #728 for updates. Thank you!
