Multilanguage

It was so easy … answered don’t remember where by plugin creator:

In Functions.php:

function hms_name_override($text) {
return 'Nombre:';
}
add_filter('hms_testimonials_sc_name', 'hms_name_override');
function hms_testim_override($text) {
return 'Testimonio:';
}
add_filter('hms_testimonials_sc_testimonial', 'hms_testim_override');
function hms_boton_override($text) {
return 'Enviar testimonio';
}
add_filter('hms_testimonials_sc_submit', 'hms_boton_override');

I am trying to accept testimonials in Hindi language and I am getting text in this manner . “????????????????????????????????????????????????”

I can use Hindi fonts on my website but not in the testimonial .
