Bidi aware formatted output

[Chris Scaife]

I'm not sure if people here want to look at developing new software, and I
see the mail system has deleted all the unicode direction controls from my
previous posts, however I did finish that output formatting algorithm for
C++ programs to use and I put it to the test localizing a little gui
program.

Attached an image showing it doing numeric base conversion in US locale and
then again in Saudi Arabia locale... That is if the mail system preserves
them.

My library has many many more localization capabilities, but in these images
it uses Middle Eastern digits. I even substituted other Arabic characters
for digits beyond 10, as shown in the duodecimal output. I'll be writing a
sequel to my internationalization.html document detailing how to use the
library in new software projects.

I also made a .po translation file but don't know any Arabic so I just put
"SA" in front of the English texts to confirm translation of the GUI is
happening. The source is in cs_lib-0.0.0.tar at
