Кодировка строк

>Понятно . Каким образом тогда узнать что передавать в качестве 2-го параметра convert_cyr_string
зачем?
ничего никуда не надо конвертить.

у тебя контент в КОИ, в метатэги - КОИ.
и данные у тебя будут в КОИ.
если кто-то умный переключит руками кодировку на UTF-8, то это уже его проблемы, а не твои.
автодетект кодировок - вещь нетривиальная, поверь.

хотя, уж если тебя это так волнует - можешь здесь смотреть _очень ненадежный пример_:

вот что я нашел на эту тему

Функция возвращает тип кодировки (смотри функцию convert_cyr_string())
или пробелл, если кодировка не определена.
Чем меньше длина строки - тем быстрее определяется кодировка.
С короткими строками возможно неправильное определение кодировки
