Exactly that: Does a strings length equal the byte size? Does it matter on the language?
I think it is, but I just want to make sure.
Additional Info: I’m just wondering in general. My specific situation was PHP with MySQL.
As the answer is no, that’s all I need know.
Nope. A zero terminated string has one extra byte. A pascal string (the Delphi shortstring) has an extra byte for the length. And unicode strings has more than one byte per character.
By unicode it depends on the encoding. It could be 2 or 4 bytes per character or even a mix of 1,2 and 4 bytes.
