[Solved] RegExp name validation using hexadecimal metacharacters

by


The range you are using is Greek extended. You want the range from 0370 to 03ff. From the page you quoted:

0370..03FF; Greek and Coptic

1F00..1FFF; Greek Extended

function is_greek(name){
    var greek = /[\u0370-\u03ff]/;
    return greek.test(name);
}

> is_greek("α")
< true
