plain terminal output

In the Steam client when text is a link, the text is not underlined when dwrite
is enabled.Installing corefonts/tahoma doesn't help.

To reproduce the issue:
1. install Steam and log in to your account.
2. open Steam->Settings->Interface menu option and toggle 'Enable DirectWrite
for improved font smoothing...' option on and off. As a result, the link
'Fluent in another language?...' above is underlined when dwrite is disabled,
but it's missing the underline when dwrite is enabled.

Plain terminal output doesn't show anything interesting, but I'm attaching it
here anyway.
