Donno about Thai but Devanagari (and any other Indic script) definitely 
has non-codepointed glyphs! See: http://www.unicode.org/faq/indic.html#17 --

Q: I cannot find on Unicode charts the "half forms" of Devanagari

A: Unicode does not encode half or subjoined letters for the scripts of 
India. Like in the ISCII standard, Unicode forms all "consonant 
clusters" (such as the "tn" in "patni") by inserting the character 
"virama" (or "halant") between the two relevant consonant letters ...
