Translate or remove escape codes from stream

[Jeff Barnes]

A couple of weeks ago, the Bug-ncurses list provided very helpful tips for 
capturing the stderr output from a library and printw'ing it to a WINDOW *.

Some of what I'm getting in the WINDOW * includes stuff like the following:

0:00:10.491677352 ^[[333m18212^[[00m  0x80efa30 ^[[32;01mINFO   ^[[00m 
^[[00;01;37;41m GST_ELEMENT_FACTORY 
gstelementfactory.c:403:gst_element_factory_create:^[[00m creating element 
"pipeline"

0:00:10.494354913 ^[[333m18212^[[00m  0x80efa30 ^[[32;01mINFO   ^[[00m 
^[[00;01;36m  GST_PLUGIN_LOADING gstplugin.c:660:gst_plugin_load_file:^[[00m 
plugin "/opt/fsmd/lib/gstreamer-0.10/libgstneonhttpsrc.so" loaded

...

Ewwwwww

If I can't translate the escape codes in a strait-forward way, the second best 
option would be to just remove them from the string that goes to the window.

Anybody know of code examples to do either?

Thanks in advance.
