escaping

I've seen a few other programs that have something like this: var string = '\x32\x20\x60\x78\x6e\x7a\x9c\x89'; And I had to try to fiddle with the numbers and letters, to find the text I wanted to display. I'm wondering if there is a function to find the \x escape of a string, like string.toUpperCase() in JS. I'm using processing JS, but it will be okay for me to use other programming languages to find the ASCII for \x . arcyqwerty If you have a string that you want escaped, you can use String.prototype.charCodeAt() If you have the code with escapes, you can just evaluate them to get the

I want to replace a string by another. I found when the replaceValue contains "$" , the replace will fail. So I am trying to escape "$" by "$$" first. The code is looks like this: var str = ..., reg = ...; function replaceString(replaceValue) { str.replace(reg, replaceValue.replace(/\$/g, '$$$$')); } But I think it is ugly since I need to write 4 dollar signs. Is there any other charactors that I need to escape? And is there any better way to do this? Leonid There is a way to call replace that allows us not to worry about escaping anything. var str = ..., reg = ...; function replaceString

I am trying to read a file into my Java program using java.util.Scanner and I get the above message when I enter the code below (I am new to java) - can anyone help? (I looked at a similar message someone got with their own code, but it was too complex for me to use in my example!). I have Windows 7. BufferedReader job = new BufferedReader (new FileReader("\My Documents\JOBS\newfile.txt")); You need to escape the "\" in the file path. BufferedReader job = new BufferedReader (new FileReader("\\My Documents\\JOBS\\newfile.txt")); \ is an escape character , use \\ If you're using eclipse, there's

I have sequences of characters I'm feeding to a decoding function: For example: "\x05three" (Yes, that's a Pascal-style string. The function translates length-prefixed strings to null-terminated strings.) I wrote a few test cases, among which: "\x04four" And to my surprise, that came out as "Oour". Looking closer, it turns out that the specification on escape sequences for Visual Studio allows that, my sequence is basically interpreted as \x04f , which would be 79 in base 10 (thus my resulting string becomes "Oour", 79 being 'O') My solution was simply to split the string: "\x04" "four" The
