Pa.nha in Khom MSS

Dear Eisel,

I searched the Paali MSS catalogues of  Vat Po, EFEO,  and the
Bibliotheque Nationale de France made by Madam Filliozat. In all  Khom
Paali MSS, pa.nha, is consistently used instead of pa~nha, e.g.,
Milindapa.nhaa, Kosalapa.nhaa.
In my Khom script tables I could not find a specific character for ~nh,
neither for .nh, so it seems to me that the origin for your problem is
not in the Sinhala script tradition, but in the Khom script tradition. I
was told that Senart's edition of the Kaccaayana is mainly based on Thai
MSS.
I hope that this is of use,
