Russian stress marks are normally omitted in general text. Dictionaries and learning materials can mark stress systematically, while ordinary writing may add an acute selectively to avoid ambiguity. [46], [9], [3]

Spelling and status
Ё and й are alphabet letters rather than optional acute stress annotations. This collection separates those letters from a set of vowel-plus-acute sequences. Gramota's spelling guidance discusses selective stress marking; a copy table cannot locate the stress in an unfamiliar Russian word. [46], [9], [3]
Distinctions to preserve
Use Cyrillic letters for Russian. Latin e and Cyrillic е may look alike but have different code points. Й canonically decomposes to Cyrillic и plus breve. A stressed vowel often remains a multi-character sequence after NFC, and no universal Alt code represents every such sequence. [46], [9], [3], [1], [2]

Searchable character table
The letter set contains ё and й in both cases. The additional vowel-plus-acute strings demonstrate stress notation, not an expanded Russian alphabet or a claim that every combination is needed in every word. [46], [9], [3], [9], [1]
