This is a suggestion to change search, so it ignores
postfix accents.
Russian dictionaries (including Wiktionary) use accents to
indicate stress on syllables, but these accents are never
seen in plain text.
In Russian Wiktionary, the verb бороться has the
inflected form боритесь (imperative, plural),
which does not have an entry of its own, but
appears in a fact box (table) of inflected forms.
However, since this is a dictionary, the word in
the box is written with an accent: бори́тесь
https://ru.wiktionary.org/wiki/бороться
(I do realize that it would be possible to add
redirect entries for all such inflected forms,
but this has not been done in ru.wiktionary.)
Searching for бори́тесь (which nobody would do)
finds the relevant page,
https://ru.wiktionary.org/w/index.php?search=бори́тесь
but searching for боритесь (the normal thing)
does not find the relevant page,
https://ru.wiktionary.org/w/index.php?search=боритесь
Note that Unicode doesn't contain accented versions
of Cyrillic letters. Instead, the accent is made
by suffixing a separate accent sign.
$ echo "и" | od -c
0000000 320 270 \n
$ echo "и́" | od -c
0000000 320 270 314 201 \n
```
Nik thinks this might be something we can get out of the unicode normalizer. We should have a look here.
