Broken font on your computer how to fix it?

Working several years in a specific program that uses a character font. Up to yesterday everything was "OK" but yesterday don't know why the font was missing most of the characters, instead of a blank cell.
Why this could happen? How to fix it? Where do "dig"?

Make a screenshot of the font, the font put in Yandex-disk (https://yadi.sk/d/exwNPeXtrpoUd).

May have installed some other version of the font, e.g. demo.
Or with all fonts right?

UPD. Pogugliv a bit on the forms post the exact same font.

Before you were instead of squares? Boov or characters?
