Performs a character set conversion on the string
str
from in_charset
to out_charset
. Returns the converted
string or FALSE on failure.
If you append the string //TRANSLIT to
out_charset
transliteration is activated. This
means that when a character can't be represented in the target charset,
it can be approximated through one or several similarly looking
characters. If you append the string //IGNORE,
characters that cannot be represented in the target charset are silently
discarded. Otherwise, str
is cut from the first
illegal character.
