charAt issue whe running in Windows

I have this small piece of code that aims to replace accented letter with no accented letters.

protected String sinAcentos(String str) {

    // Cadena de caracteres original a sustituir.
    String original = "áàäéèëíìïóòöúùuñÁÀÄÉÈËÍÌÏÓÒÖÚÙÜÑçÇ";
    // Cadena de caracteres ASCII que reemplazarán los originales.
    String ascii = "aaaeeeiiiooouuunAAAEEEIIIOOOUUUNcC";

    String tmp = str;
    for (int i=0; i<original.length(); i++) {
        // Reemplazamos los caracteres especiales.
        tmp = tmp.replace(original.charAt(i), ascii.charAt(i));
    }//for i
    return tmp;
}

When I run this function from within IDE (eclipse) there is no error. But then I export an create an executable product, that runs on Windows 7 and also Windows XP.

When the function runs an error occurs and the text is:

Index out of bounds:34

So, 34 is the lenght of original string variable. therefore the loop shoul loop i between 0 and 33 , because the loop condition : i < original.lenght() ...

I change the code adding a try...catch at the replace line, and that's how is working now.

Any idea what's wrong in the code?

Please check the encoding of your Java source file and also check the charset used for both Strings.

There might be a mismatch between those and some encodings require more bytes than others for special characters (think UTF-8 vs. ISO-8859-1 for example).

Make sure that your Java source file is using UTF-8 and not ISO-8859-1 or a Windows-specific encoding like CP-1252.
