The new Skype for Android (version 22.214.171.12447) is fast and beautiful. The only thing missing is a fully supported unicode typeface for languages like Vietnamese (my mother tongue). So I swap Segoe WP for Segoe UI for good.
The new Chatheads feature of Facebook Messenger (Android) is cool but the engineers at Facebook are cold enough to use Helvetica Neue — being a typeface that does not support Unicode characters (like Tiếng Việt). So I recompiled the app using Google’s own Roboto for good.
Download and enjoy: Facebook Messenger with Unicode support.
