Слетают шрифты на сайте после настройки редиректа в нижний регистр. Как быть?
привожу пример настройки в htacces и подключения шрифтов в CSS

Как можно этого избежать?
Неужели только переименовывать файлы шрифтов?

код в htaccess

RewriteEngine On

# Replace single occurance of CAP with cap, then process next Rule.
