ASCII CODE problem- a.s.a.p

[solal]

How do I convert ASCII value into a letter/number/...
and the opposite?

in Pascal it's: ORD & CHR function, what are the functions in Javascript?

[glenngv]

ascii = 65;
alert(String.fromCharCode(ascii));// gives A
str = "blah";
alert(str.charCodeAt(0)); //gives 98 which is the ascii code of b

Glenn, I wonder, is there such a pair of functions for unicode?

I was searching for the unicode thing too. I wish I could replace the page worth of code by a line or two. LOL

...those functions work just fine for me :D

they deal with codes up to 16-bit (0 through to 65535) and display all the relevant unicode sets.

so... what's the problem?

What's the syntax you used? Like if I wanted to insert a tab from the string

"\u0009"

?

[krycek]

String.fromCharCode seems to work fine.

like, String.fromCharCode(9)

I don't use this stuff just generally, I use it for my compression algorithms, but I do an output of the compressed string, and the chars are as expected. Like, some chinese and weird letters etc. And tabs work fine.

Try it! :)

Ao, all the low-number unicode chars are identical to the ASCII version? In that case, you really aren't expressing them as unicode...are you?

as far as I know, yes you are.

unicodes 0 thru 127 are identical to ASCII (correct me if I am wrong)

hence u0009 = ascii 9

as I understand it, the point of unicode is to allow extra charsets to be used. those charsets start AFTER the default ASCII values have finished... otherwise, how would it all be compatible?

control chars have to remain the same, hence unicode 0-127 = ASCII :)

simple :)
