Return unicode of a character

kookh · 29th August 2006, 12:49

Is there a function in NSIS that can return the unicode of a certain character? Something similar to charCodeAt() in JavaScript?

You can use the System plug-in to convert strings into Unicode. There are many ways to do that, even with that plug-in. If you provide a little more details about what exactly you're trying to do, I can show you the best solution for the problem.

Edit: I just need to loop on every character in a string, obtain its unicode value, and do some operation on it.

Build a Unicode string and read it 2 bytes at a time.

code:
System::Call "*(&w1024 'hello')i.r0"

StrCpy $1 $0

System::Call "*$0(&i2.r2)"

${While} $2 != 0

  DetailPrint $2

  IntOp $0 $0 + 2

  System::Call "*$0(&i2.r2)"

${EndWhile}

System::Free $1
