you can use the escape() value to split the string. for ± I found two values (maybe there are more?).
var string = escape('test±test2±test3'); var split = string.split('%C2%B1'); alert(split); // test,test2,test3 // %B1%0A is the value i found for ± // %C2%B1 is the value escape() gives me when i just copy and paste that char :)
