Today, the official written language in Russia for the Evenki language is Cyrillic script. The script has one additional letter, ӈ, to indicate /ŋ/; it is used only inconsistently in printed works, due to typographical limitations. Boldyrev's dictionary uses ң instead. Other sounds found in Evenki but not Russian, such as /dʒ/, lack devoted letters. Instead д stands in for both /d/ and /dʒ/; when the latter pronunciation is intended, it is followed by one of Cyrillic's iotified letters, similar to the way those letters cause palatalization of the preceding consonant in Russian. However orthographic decisions like these have resulted in some confusion and transfer of Russian phonetics to Evenki among younger speakers. For example, the spellings "ди" and "ды" were intended to record and [di (i.e. the same vowel sound). However, in Russian "и" and "ы" are respectively two different vowels /i/ and /ɨ/. Long vowels are indicated with macrons.
