The language name is ᐄᔨᔨᐅᔨᒧᐧᐃᓐ (iiyiyiuyimuwin) in the language and East Cree in English if I check this https://www.eastcree.org/cree/en/dictionary/
https://www.wikidata.org/wiki/Q282011
They use the canadian Aboriginal syllabics
The language is used by the cree people in Quebec.
I note they are two codes for East Cree (crj ans crl), but the https://www.atlas-ling.ca/ seem to consider them as a unique language. they use the same syllabic convertor https://syllabics.atlas-ling.ca/ The dictionnary is divided by the two dialect https://dictionary.eastcree.org/words, but they use the same site at the difference of the other algonquian language dictionnaries. If I look http://www.endangeredlanguages.com/lang/2165, the distinction between the two seem the varies by your sources.
