m-bib issues

[ishamid <ishamid@lamar.colostate.edu>]

Dear knights of the round table,

I've been using a very old bib module up to now, with lots of personal tweaks, 
workarounds etc. (mission-critical issues--no time 2 deal with painful 
upgrades); now I'm starting fresh with the latest. Here is one issue:

The \startpublication[a= ] option seems to cause m-bib to choke on some 
accents. Here is an example:

============test-bib.bbl===============
\startpublication[k=ahsaif,
                  t=book,
                  a=\AHSAI,
                  y=1856,
                  s=\AHSAI1856]
%\author[\v Say\h h]{A\.hmad Ibn Zayni \Al-D\={i}n}[A.]{}{\Ah}
\author[\v Say\h h]{A\.hmad Ibn Zayni \Al-D\={i}n}[A.]{}{\Ah}
\title{\v Sar\.hu \~al-Faw\={a}\'id}
\pubname{n.p.}
\city{Tabriz}
\pubyear{1856}
\stoppublication

\startpublication[k=ahsaijk,
                  t=book,
                  a=\AHSAI,
                  y=1856--59,
                  s=\AHSAI1856--59]
\author[\v Say\h h]{A\.hmad Ibn Zayni \Al-D\={i}n}[A.]{}{\Ah}
\title{Jaw\={a}mi\`u \~al-Kalim}
\pubname{n.p.}
\note{Two volumes}
\city{Tabriz}
\pubyear{1856--59}
\stoppublication
=======================================

and here is the accompanying tex file

============test-bib.tex===============
\setupoutput[pdftex]

\usemodule[bib]

\def\AHSAI{A\d hs\=a'\~\i}
%\def\AHSAI{A\d hs\=a'i}

\input test-bib.bbl

\starttext

\cite[ahsaif]

\cite[ahsaijk]

\stoptext
=======================================

In this example the \startpublication[a= ] option chokes on \~.

Any help/chivalry will be appreciated!
