How to teach Mail App in Win 10 to substitute email addresses in the To: line by the first letter?

Question

Windows

That is, it can do this, but only by the first LATIN letter in email. And for example, the Yandex web client can use both Latin and Cyrillic alphabets in the associated name in the address book. I saw that it is recommended to switch the application language to Russian (but then the whole Windows will switch to Russian, right?) And then, thinking logically, the possibility of setting it in Latin will disappear.
