PHP - mb_internal_encoding

Metóda - mb_internal_encoding
(PHP 4 >= 4.0.6, PHP 5, PHP 7)
To work with strings, it is important for PHP to know our encoding. We will usually (actually everytime) use UTF8. The advantage of Unicode (i.e. UTF encoding) is that we do not have to worry if the user inserts Czech, Cyrillic or something else. It is all always shown correctly. On the other hand, the disadvantage is that special characters (for example Cyrillic characters) are saved as more characters in the string. They do not take 1 byte as other characters but they are actually e.g. 2 letters (we can imagine the caron and the c letter for a character of č). We talk about so-called multi-byte characters.
We set UTF encoding via the function mb_internal_encoding().
