Asana Math calligraphic capital R with XeTeX

Question

I am having problems getting a calligraphic ‘R’ with Asana Math.

This is my minimal:

\font\asanacal="Asana Math:script=math;mapping=script;+salt"
\font\asanascr="Asana Math:script=math;mapping=script"
\textfont2=\asanacal
\textfont6=\asanascr

$ \fam2 ABCDEFGHIJKLMNOPQRSTUVWXYZ $

$ \fam6 ABCDEFGHIJKLMNOPQRSTUVWXYZ $
\bye

I get a script R instead of calligraphic R.

This is my script.map:

LHSName "script"
RHSName "UNICODE"
pass(unicode)

Answer 1

Two issues here, first you need to pass script=math in the font definition since this features is registered with the math OpenType script tag, second script R is missing from Asana’s salt feature (bad luck :)), others seem to work fine.
