bash printing extended ASCII characters
I'm trying to print ? ? ? and other extended ascii character in bash using printf, but they don't seem to be regonised. The syntax I'm using is
printf "\###" where ### is the octal value for the character. Does anyone know if extended ascii is supported in bash and if so how to print the characters to the screen? Thanks |
That depends a little of the font used in terminal (what do you call extended ascii ?)
Try (in hexa) : echo -e "\xA9" and in octal : echo -e "\0251" |
I've been programming for a few years and I never knew that 'extended ascii' was so ambiguous, but now I've done some reading I realise there is no such thing.
When I say extended ascii, I guess I mean IBM DOS extended ascii. Have a look at http://www.lookuptables.com/ there is some 'extended ascii' at the bottom. |
Lol, I see... For me this is just ascii (but I don't program for a few years, just the last one)
I would say again that the display of these chars depends of the terminal font, eg if the char won't display, it may means that this char is not built in the font. |
I've been reading something about codepage. That might have something to do with it. bash has something there about 127, I'm just doing a script to find out what it is, I'll let you know.

Well nothing too good. Below is a list of the ascii code outputs through printf from 0 to 400. The left column is the octal code, the right is the output. Hope this helps someone out, because it helped me squat ;)

It should be more educative to post code than result of script
Something like: Code:
#!/bin/bash |
