Validating SharePoint file names in JavaScript

SharePoint limits the valid characters of file names, which can be a problem, so to prevent this issue, we use this function to validated filenames in our Web App that integrates with SharePoint.

var validateFileName = function (value){

var specialCharacters = new RegExp("[\\\\\/:*?\"<>|#{}%~&]");

if (specialCharacters.test(value)) {      
 return true;
}
else{
 return false;
}

}

Only thing to note is that \\\\ is needed to represent \ in the regular expression, see this for more details
