If you want to send a non-Latin script text message to a mobile phone, do it via the web. The South African firm SMSWarehouse is tryng to extend market share by offering a Unicode-based texting service on its web site. You log in, select a virtual keyboard for the script of your choice (Arabic, Greek, Russian, Chinese etc), and tap out your message. It displays the other end on a script-compatible mobile phone. This enabling loop via the web is a clever wheeze, but you’d expect most texters would want to operate straight from a mobile phone themselves.
