Just curious.

Can we highlight like telephone numbers by creating an *extra* dash,
space or a point.

Tel no: 1234567890 rendered as
Tel no: 12345-67890

In some ways, the highlighting as seen above is in-band and not
out-of-band (as underlines are).  It is also naturally how one would
write down long numbers on a piece of paper for ease of reading.
