Convert ASCII strings to Unicode-style (with hex 00 between ASCII numbers)

Recommended Posts

I think this should be easy, but I've searched and experimented without success.

I want to be able to convert an ASCII string that looks like this:


Into a unicode-style string with hex 00 between each of the ASCII numbers, like this (for the first few characters):

00 43 00 3A 00 5C 00 50 00 41 00 54 ...

There is some ancient code on the forum that only converts the first five or six characters, and, as far as I can tell, the various _WinAPI_ functions won't accomplish this with plain-ASCII strings.

Am I missing something obvious? I'll be grateful for any help in making this work.

#include <fileconstants.au3>

Local $str = "C:\PATHTO~1\FILENAME.EXT"
Local $new = StringToBinary($str, 3)

; or

Local $hOut = FileOpen("myfile.txt", $FO_OVERWRITE + $FO_CREATEPATH + $FO_UTF16_BE)
FileWrite($hOut, $str)
; ...
