Re: Bolding a phone prefix in a rule
The Gotham family doesn't "allow" bolding or italicizing, you have to call out the specific flavor of the font.
Instead of <b>T</b> try:
<f name=Gotham Bold>T<f name=Gotham Book>
Depending on how your rule is written you might need to write it like the following:
+ '<f name = "Gotham Bold">T</f>' +
