Dear Hans and gang,

I got this working in mkii -- using other macros --, but mkiv is  
frustrating me:

======================
%% Hans' bottom accent code
\unprotect
\unexpanded\def\bottomaccent#1#2#3#4#5% down right slantcorrection accent  
char
   {\dontleavehmode % why this align mess
    \vtop
      {\forgetall
       \baselineskip\zeropoint
       \lineskip#1%
       \everycr\emptytoks
       \tabskip\zeropoint
       \lineskiplimit\zeropoint
       \setbox0\hbox{#4}%
       \halign
         {##\crcr\hbox{#5}\crcr
          \hidewidth
          \hskip#2\wd0
          \hskip-#3\slantperpoint % in plain 1ex * dimenless value
          \vbox to .2ex{\box0\vss}\hidewidth
          \crcr}}}

	  \unexpanded\def\buildtextbottomdot
	  {\bottomaccent{0ex}{4}{5}{\kern.1em\textbottomdot}}
\let\d\buildtextbottomdot
\protect

\defineactivecharacter ḥ  {\d{h}}

\starttext
ḥ {\it ḥ}
\stoptext
======================

I need to adjust the horizontal position of the dot under the slanted  
char. I would assume the third parameter would control it but nothing  
seems to work.

Of course LM does not look so bad but I'm using a different font so this  
is just an illustration.

Best wishes
Idris
