Special characters on Windows bridge docs are breaking the translation pot

When I run Lektor server I got a bunch of errors on this page: https://community.torproject.org/relay/setup/bridge/windows/

For example:

i18n/contents.pot generated i18n/contents.pot:7351:192: invalid control sequence i18n/contents.pot:7351:198: invalid control sequence i18n/contents.pot:7351:205: invalid control sequence i18n/contents.pot:7351:213: invalid control sequence

The probably reason is because we have strings like C:\.
