yes, but calling this a normal font is somewhat over-the-top

(1) the left/right () are not part of the lookup, and they are not even 
in the font: imo they should be, and also be part of the lookup then

(2) you cannot expect other digits to work well as *all* become 
ornamented, so the font is only useable for special purposes (for which 
it might lack other niceties)

(3) the <arabic number> * n are mapped onto a ligature (lots of them are 
available in the font, upto a certain number)

(4) so, also a single digit is a ligature and (mostly because i have all 
kinds of tracing depending on cases, i never expected that one to happen 
so it was not done at all)

At least I now see the odd cases and keep an eye on them. It's also 
another demo that traditional font terminology - like 'ligature' - in 
opentype usage / implementation is rather useless.

I uploaded a beta that fixes the 
single-substitution-disguised-as-ligature but be aware of the fact that 
it's a somewhat weird font so watch your input.
