extended ascii chars and ansi in the mac osx terminal app

Question

i wanted to create some shellscripts that display pretty ansi colored graphics for osx but unfortunately i find just very little information about that topic.

1. osx seems to use monaco 10 as its default console font. is there some way to find out all displayable characters for this font?
2. osx terminal runs in UTF-8 per default as far as i found out (can somebody confirm this?)
3. is there a way to show or enter the extended ascii characters on osx (how it was done on windows/dos with alt gr+entering the digits)

thanks!

Answer 1

Extended chars ar usually hused thorugh option+character key and shift+option+character key. I beleive terminal is utf-8 by default. Monaco should support the compelete character map. If you open up FontBook you can gain access to the char map there.

Additionally you can customize a lot of this type of thing from the preferences pane for terminal.

In Bash, you should be able to do:

for i in {32..255}; do printf "$i "\\$(($i/64*100+$i%64/8*10+$i%8))"\n"; done | column

to get a table of ASCII characters.
