Convert string to special characters you want using replace() function in javascript. Useful when converting characters to be saved in the database or passed as a parameter in a url.

function convertSC(oldstring)
{

oldstring = oldstring.replace(/_DQ_/g, “\”");
oldstring = oldstring.replace(/_SQ_/g, “‘”);
oldstring = oldstring.replace(/_@_/g, “&”);
oldstring = oldstring.replace(/_AND_/g, “&”);
oldstring = oldstring.replace(/_LT_/g, “<");
oldstring = oldstring.replace(/_GT_/g, “>”);
oldstring = oldstring.replace(/_PC_/g, “%”);
oldstring = oldstring.replace(/_DQ_/g, “\”");

return oldstring;
}

Example:
var convertme = convertSC(“Total is 100_PC_”);
alert(converme);

Output:
Total is 100%

function convertSC(oldstring)
{
newstring = oldstring.replace(/\”/g, “_DQ_”); //double quote
newstring = newstring.replace(/’/g, “_SQ_”); //apostrophe
newstring = newstring.replace(/&/g, “_@_”); //ampersand
newstring = newstring.replace(/\%/g, “_PC_”); //percentage

return newstring;
}

Example:
var convertme = convertSC(“hello world and hello universe”);
alert(converme);
