In codepoints, <U+0644 LAM, U+0651 SHADDA, U+064E FATHA> to <U+0644,<br>
U+064E, U+0651>. No process compliant with Unicode shall *deliberately*<br>
render them differently - the sequences are canonically equivalent.<br>

This sequence is <U+644, U+651, U+650 KASRA>, which is not canonically<br>
normalised. Using the Naskh font Amiri, kasra is by default placed below<br>
lam. However, if I enable OpenType feature ss05, which for this font is<br>
described (unless the labels have been scrambled) as "Kasra is placed<br>
below Shadda instead of base glyph", the kasra is indeed placed<br>
immediately below the shadda. Unicode allows both renderings.<br>
<br>
I'm not sure that Unicode provides any plain text mechanism to<br>
distinguish the two renderings.<br>
<br>
In answer to Eli, the Amiri font is the one I downloaded to<br>
get LAM and HAH to automatically ligate; I got it from Ubuntu package<br>
fonts-hosny-amiri. The font is published under the SIL Open Font<br>
Licence.<br>
