\sl \the\fontdimen1\font\the\dimexpr1em\relax \`A \'A

\it \the\fontdimen1\font\the\dimexpr1em\relax \`A \'A
i can imagine that we start building a database with additional font parameters
I spent a few hours on a workaround. Attached is my temporary code for Arabic transliteration. I found a way to define U-02BE and U-02BF for Latin Modern (thanks to Wolfgang and Peter for helping me with \ifx). It does work well but feel free to suggest improvements!

use \normalhbox cum suis when you want to use showboxes (which overloads the primitive box operations) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
