identify encoding from a file

[Marios lyberak]

Hello community,

i have a file which is generated out of an old Paradox database,

and i try to figure out what is the encoding of these strangely represented
characters

in <RECORD ID="5">

<GROUPNAME>̡觴ݲ</GROUPNAME> -> <GROUPNAME>Μαθητές</GROUPNAME>

and in

<RECORD ID="6">

<GROUPNAME>ʡ解紝</GROUPNAME> -> <GROUPNAME>Καθητητές</GROUPNAME>

Our goal is to convert the attached file to a UTF encoding, so as the
characters be readable in greek.

Thank you in advance all
