ISO_1 is provided for compatibility with the Adaptive Server Enterprise default ISO_1 collation.
The differences are:
- ß, the lowercase letter sharp s (\xDF), sorts after lowercase s in SAP Sybase IQ and SAP SQL Anywhere, but after ss
in Adaptive Server Enterprise.
- The ligatures corresponding to Æ and æ (\xC6 and \xE6) sort after A and a
respectively in SAP Sybase IQ and SAP SQL Anywhere (A, a, æ, Æ). In Adaptive Server Enterprise the sort order is A, a, Æ, æ.
