mb_convert_variables() convert
character encoding of variables
vars in encoding
from-encoding to encoding
to-encoding. It returns character encoding before
conversion for success,
FALSE for failure.
mb_convert_variables() join
strings in Array or Object to detect encoding, since encoding
detection tends to fail for short strings. Therefore, it is
impossible to mix encoding in single array or object.
It from-encoding is
specified by array or comma separated string, it tries to
detect encoding from
from-coding. When
encoding is omitted,
detect_order is used.
vars (3rd and larger)
is reference to variable to be converted. String, Array and
Object are accepted.
mb_convert_variables() assumes all parameters have the
same encoding.
