* composed (NFC).
*
* In general what happens is that: each grapheme is decomposed in a chain
- * of 1:2 decompositions, marks reordered, and then recomposed if desires,
+ * of 1:2 decompositions, marks reordered, and then recomposed if desired,
* so far it's like Unicode Normalization. However, the decomposition and
* recomposition only happens if the font supports the resulting characters.
*
* though their NFC may be different.
*
* - When a font has a precomposed character for a sequence but the 'ccmp'
- * feature in the font is not adequate, form use the precomposed character
+ * feature in the font is not adequate, use the precomposed character
* which typically has better mark positioning.

* - When a font does not support a character but supports its decomposition,
