Unicode to binary.

[Godd]

I need to be able to convert unicode text to binary for a program I'm writing.

I've looked through the entire binascii library but I can't find what I need.

I can go through unicode to hex to binary, but the binary comes out to something unusable.

\xf0Y\xfa\xc3_\x8bn/\x8d>\x88\xd7\xe2

Something along the lines of that. What I need is just ones and zeros for on and off status.

I think I can do it by using a list to reference to numerical values but a function would be much nicer and faster.

You just want to convert unicode text (i.e. \u0065) to the binary number (in 0 and 1 format)?

There is the non-portable C extension to printf using the %b format specifier which prints binary representations of numbers. You could do this with:



static char *buffer[1024*5];

char *u2bin(wchar_t *text)
{
int ctr = 0;

while (text[ctr] != L'\0') {
sprintf(buffer+(ctr * sizeof(wchar_t)), "%b", text[ctr]);
ctr++;
}
buffer[ctr] = '\0';

return buffer;
}


I *think*, although there is some type coercion going on there (with the wchar_t to an int, I think, though on UNIX these should be the same).

Ha. I've never even begun to code in C.

I have a friend that may be able to help. But Could someone explain the general idea?

so what programming language r u using to write the program? or is it just a shell script u r trying to create?

[Godd]

Sorry bout reanimating a dead thread but I wasn't able to get to my comp for a few days.

I can't believe I didn't post the language I was programming in on the initial post.

That would be python. Sorry about that.

Is this close?
