From 59d038d591f7f00e6752cbfadbbc1c0ca318c5c0 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 20 Apr 2012 16:26:14 -0300 Subject: ui browser: Add method to write graphical characters To save typing on the switch char set slang stuff. It also helps in removing more slang direct calls, wrapping them at the ui_browser level, where at some point I'll try to implement those in terms of GTK+.
