I have been installing Oracle database instances since 8i and essentially use the Unicode for Arabic so I was intrigued and wanted to clarify.

Note that AL32UTF8 was the default for the 11g also as I checked my installation notes. Did not check the 10g installation notes yet though.

I installed 8i, 9i, 10g, 11g, 12c, 19c (on Linux) and 21c (Express Edition) so far

Regarding CHAR semantic see https://dblinter-rules.united-codes.com/rules/G-2340/.

Regarding the character set. AL32UTF8 is the default since Oracle Database 12c Relase 2. Here’s an excerpt from the Database Globalization Support Guide 12c Release 1:

Starting from Oracle Database 12c Release 2, if you use Oracle Universal Installer or Database Configuration Assistant (DBCA) to create the database, then the default database character set is AL32UTF8.

IMO this default is good and should not be changed.
