Ya with diaeresis is used in the Selkup language.

In Russian, ya with diaeresis saw rare use prior to the 1918 orthography reform to indicate that a stressed letter ya (Я) should be pronounced as /jo/ instead of the expected /ja/, in a similar fashion to the role of yo (Ё).[1] For example, the modern pronouns её and неё were formerly spelled ея̈ and нея̈ in the genitive and possessive, due to their historical pronunciations as /jɪˈja/ and /nʲɪˈja/, which had since shifted to /jɪˈjo/ and /nʲɪˈjo/. As with the letter yo, use of the diaeresis was rare outside of learning materials and dictionaries, and following the reform the letter was replaced with yo outright.
