How to choose the right encoding when converting from a php file to html?

Question

PHP

Good evening.
I have a php file that receives information from a server. I need to save this file in html. There is one problem: the text on the page is in Ukrainian. When converting with the ob_start(), ob_end_flush() and ob_get_contents() pods, the encoding is converted to utf-8 and the text is displayed as characters.
How to set up the encoding correctly?
What classes can perform this task?

Answer 1

iconv("windows-1251", "UTF-8", $html);
where in $html is the text in the encoding you want to change..

Answer 2
