On page 136 of The Firebird Book Second Edition: "NCHAR VARYING(n) ..., is a specialized implementation of VARCHAR(n) that is pre-defined with ISO8859_1 as its character set attribute"
Are there any performance advantages of using nchar varying instead of varchar ? If not are there any other advantages in addition to the pre-defined ISO8859_1 charset ? I am using firebird 3.0.1 on Windows 10. Thank you for your attention. Observations: 1. This is my first post to the mailing list. I have tried through the yahoo groups web interface yesterday but today I was unable to find my own question so I am posting directly via e-mail. Please accept my apologies if this caused a duplication. 2. English is not my native language so please accept my apologies for any eventual mistakes.
