leuce Posted October 17, 2020 Share Posted October 17, 2020 Hello everyone I have text files that use "private use characters", and I would like to find all those characters and replace them with a single, known character. As far as I can tell, the files do not use the full range of 6000 private use characters, but only ones whose codes start with "E". This means that I can identify these characters easily by simply checking every 4th 'byte' (I'm not sure if 'byte' is the right word) to see if it is an "E", and then replacing it and the next 3 'bytes' with something else, e.g. 24EA. I attach an image of what the two lines of text look like in two of my local text editors (since the characters won't show up correctly here in the forum). All I need to do now is to convert "0x007B24EA24EA007D" to "{⓪⓪}", and I'll be a happy camper. How do I do that? #include <StringConstants.au3> $foo = "0x007BE103E111007D" MsgBox (0, "", $foo, 0) MsgBox (0, "", BinaryToString ($foo, 3), 0) ; should display {} $len = (StringLen ($foo) - 2) / 4 $position = 3 For $i = 1 to $len If StringMid ($foo, $position, 1) = "E" Then $foo = StringReplace ($foo, $position, "2", 1) $foo = StringReplace ($foo, $position + 1, "4", 1) $foo = StringReplace ($foo, $position + 2, "E", 1) $foo = StringReplace ($foo, $position + 3, "A", 1) EndIf $position = $position + 4 Next MsgBox (0, "", $foo, 0) ; should display 0x007B24EA24EA007D ; And now I need to convert $foo to {⓪⓪}, but this doesn't work: MsgBox (0, "", StringToBinary ($foo, 3), 0) Thanks Samuel (By the way, if you know of an easier/faster way to find characters of a certain code range in a text file and replace them all with a single character, I'll be happy to hear about it.)

leuce Posted October 17, 2020 Author Share Posted October 17, 2020 Nevermind, I discovered that I should have used: MsgBox (0, "", BinaryToString ($foo, 3), 0) ...as the last line. Link to comment Share on other sites More sharing options...
jchd Posted October 18, 2020 Share Posted October 18, 2020 $foo = "0x007BE103E111007D" MsgBox (0, "", $foo, 0) $sIn = BinaryToString($foo, 3) MsgBox (0, "", $sIn, 0) ; should display {} $sClean = StringRegExpReplace($sIn, "[\x{E000}-\x{F8FF}]", "⓪") ; private area range --> ⓪ MsgBox (0, "", $sClean, 0) This wonderful site allows debugging and testing regular expressions (many flavors available).
