[NTG-context] lb bar/Unicode 2114 symbol

Hello, I'm using the following encoding commands \usetypescript[modern-base][texnansi] \setupbodyfont[12pt,modern] and was wondering whether someone knows an elegant way to get the pound sign 'lb bar' (unicode #2114, html ℔). My current hack looks like this: \def\lbbar% {% \raise.28em\hbox{--}% \kern-.535eml% \kern-.1emb% } but I'm underwhelmed by the thinness of the bar ... Thanks for any insights, Joh
