Stephen,
Or use the double braketting bars
Cell[TextData[{
"This is a scalable norm constructed using the \"esc l || \
esc\",(RightDoubleBracketingBar), and \"esc r || esc\" \
(DoubleBracketingBarcharacters) on the Basic Typesetting \
pallette ",

RowBox[{"\[LeftDoubleBracketingBar]",

StyleBox[

TraditionalForm]]]
