Status and history for guj

Is it true that it is common (65 occurrences in this document) to find a vowel LETTER in the middle of a word?

September 7, 2006		[Eric Muller] the document provided has 65 occurrences of U+200C ZERO WIDTH NON-JOINER, all after some cluster and before a VOWEL LETTER. Removed those, since they are useless there.
