ISO 8859-7
From Just Solve the File Format Problem
ISO 8859-7, aka Latin/Greek, is an encoding of the ISO 8859 family for Modern Greek. A 2003 revision added the drachma, euro, and ypogegrammeni characters without changing any existing codes. The revision is technically called ISO/IEC 8859-7:2003.
The 8859-7 encoding incorporates the ASCII characters in the first 128 code points (0-127), including the C0 controls.
