I can't actually reproduce the described behavior, because it triggers a syntax error on my setup.

Anyway, character sets can't be auto-magically guessed (not to mention that they can be mixed), so you can't expect case-sensitivity to work out of the box like that. However, the following should work:

    <?php
    declare(encoding='WINDOWS-1251'); // assuming this is the file character set

    function тест() { echo "ok\n"; }

    тест();
    ТЕСТ();

It doesn't. As I said - it triggers a syntax error for me and doesn't recognize the characters at all.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
