Inno Setup Reading file in Ansi and Unicode encoding

Question

I have a function called GetServerName. I need to pass the file name (say for example \'test.txt\') as well as a needed section string (say for example \'server

Answer 1

First, note that the Unicode is not an encoding. The Unicode is a character set. Encoding is UTF-8, UTF-16, UTF-32 etc. So we do not know which encoding you actually use.

In the Unicode version of Inno Setup, the LoadStringsFromFile function uses the current Windows Ansi encoding by default.

But, if the file has the UTF-8 BOM, it will treat the contents accordingly. The BOM is a common way to autodetect the UTF-8 (and other UTF-*) encoding. You can create a file in the UTF-8 encoding with BOM using Windows Notepad.

UTF-16 or other encodings are not supported natively.

For implementation of reading UTF-16 file, see Inno Setup Pascal Script - Reading UTF-16 file.
