<p>
For example, in Tamil, when the letter "TTA" (ட)
- letter is followed by "U" (உ), the pair
+ letter is followed by the vowel sign "U" (ு), the pair
must be replaced by the single glyph "டு". The
- sequence of Unicode characters "டஉ" needs to be
+ sequence of Unicode characters "ட,ு" needs to be
substituted with a single "டு" glyph from the
font.
