DIN 66003

The German standard DIN 66003, also known as Code page 1011 (CCSID 1011; abbreviated CP1011) by IBM, Code page 20106 (abbreviated CP20106) by Microsoft and D7DEC by Oracle, is a modification of 7-bit ASCII with adaptations for the German language, replacing certain symbol characters with umlauts and the eszett. It is the German national version of ISO/IEC 646 (ISO 646-DE), and also a localised option in DEC's National Replacement Character Set (NRCS) for their VT220 terminals.

It is registered with the ISO-IR registry for use with ISO/IEC 2022 as ISO-IR-21. Kermit calls it GERMAN, but also accepts the IANA-registered name ISO646-DE. Other IANA-registered names include DIN_66003, csISO21German and simply de.
