customHelper language specific characters

[dbvcode]

Hello,
I made a project with handlebars. It works great and does what it has to do.
The only problem I have is that with a custom helper I do not get the language specific characters thru.
For the sake of simplicity this is what I have:

Handlebars.registerHelper('html10n', function (str) {
    return "ß ăî ومض";
});

I call it with:
{{html10n "blablabla"}}

Unfortunately I get this output: � ?� ???

Even worse than this is that on http://tryhandlebarsjs.com/ my helper works flawlessly and the ouput is ß ăî ومض
Do you have any pointers on this?
Thanks.

It was my bad.
I have placed the registerHelper() in a file that was ANSI encoded.
It works as expected.
