hi slav,

this is not particularly related to misultin. when using uri you need to
ensure that these are properly encoded for HTTP. You also need to ensure
that the browser is rendering html encoded in UTF-8 so you should have in
your code:

% handle a GET on /users/{username}
handle('GET', ["users", UserName], Req) ->
    Req:ok([{"Content-Type", "text/html; charset=UTF-8"}], "This is ~s's
page.", [UserName]);

then, you may serve the page:


that will print;

This is Привет's page.

you probably also could read into IRI: http://tools.ietf.org/html/rfc3987

my 2c.
