This is true.  Cursors do not show up well in Indic aksharas because of things
like half forms, subjoined consonants, and non-spacing vowels (plus RA).

There are ways to simulate cursor motion through an akshara (cluster).
Underlining the separate pieces, for instance, as the cursor key is pressed,
leaving the I-beam cursor in one place.

Correct.  When moving forward, the internal cursor moves over the LAM and ALIF
characters while the external cursor moves over the single ligature (grapheme)
of LAM-ALIF.
