Hello All,
When testing koha 3.16.01 SIP using telnet by trying to run this command

2300120080623    172148AOCL|AA123456|ACsipstation01|ADbadpassword

we get the following result

24YYYY      YY  00120141224    055624AE???? ????|AA123456|AFGreetings from
Koha.

where (???? ????)  is an Arabic name of the user, We are asking why the
Arabic names appear as question marks.

Thanks.
