SAP UNICODE NAMES documentation, setup help and example usage

ARTICLE

Names in Unicode Programs
Only the following characters are allowed in names in Unicode programs:
The letters "A" through "Z"
The digits "0" through "9"
Underscores ("_")
For compatibility reasons, the characters "%", "$", "?", "-", "#", and "*" can also be used but only in exceptional cases (for example, for existing program generations) and with good justification. Forward slashes ("/") can also be used for namespace prefixes. The program DEMO_CHARACTERS_IN_ABAP_NAMES
demonstrates how these checks run in the current system.

Note
Outside of ABAP Objects, non-Unicode programs can also use characters other than the ones listed above. This can cause the following problems in these programs:

If characters are used that are not available in all code pages supported by SAP, it might not be possible to run certain programs when using a code page other than the one in which they were created.

No string templates can be used in a non-Unicode program.
