UniCode supported
From Zenitel Wiki
UniCode as UTF-8 currently support for the DIP protocol:
AlphaCom ISO-1 characters mapped to UTF-8 except for the following special cases:
AlphaCom Decription UniCode Value 0x80 down-arrow 0x2193 0x81 up-arrow 0x2191 0x82 right-arrow 0x2192 0x83 left-arrow 0x2190 0xA0-0xBA Hebrew 0x5D0-0x5EA
Hebrew is only remapped when Hebrew MDF is used. Else the ISO-1 byte is coded as plain UTF-8.
