How to send special chars?

Hi,

I need to send chars as € (euro), á (aacute),... without using unicode because when I use unicode message maxlength becomes much shorter than initial 160 chars, so one message is splitted in two or more messages, and that has a cost.

Is there any solution? The only way I found is to replace those chars before sending the message, for example: € replace with E, á replace with a

Thank you a lot.

Hi,

You should using converter from ISO or UTF8 to GSM characterset.
Here is the example from me.

# set class
class GsmCharacterSetConverter {

# public member area
#**************************************************
# convert iso to gsm character *
# @param string *
# @return string *
# $this->onvertCharacters($string) *
#***************************************************

public function convertCharacters($string) {
# set iso latin 1 to gsm character in array
$iso8859ToGsmCharacterSet = array (
