The difference between these two sets (both in Quebec)does not
represent a difference in pronunciation. Diacritics show altered
vowel length, labialization and preaspiration of consonants. Each
syllable is encoded separately if the vowel length or labialization
differs, even though the unpointed, shown in set 2 is the usual
written style. In Ontario it is popular to point to disambiguate.
The Cree of Ontario are not ready to publish a syllabics dictionary
yet - no surpise!
It seems to me that there would be many encodings possible for any
one word, depending on how one wanted to point it, like set 1, set
2, or something in between. How many possible encodings would there
be for the word "legend"?
