Insert EBCDIC character into javascript string

Question

I need to create an EBCDIC string within my javascript and save it into an EBCDIC database. A process on the EBCDIC system then uses the data. I haven't had any problems until I came across the character '¬'. In EBCDIC it is hex value of 5F. All of the usual letters and symbols seem to automagically convert with no problem. Any idea how I can create the EBCDIC value for '¬' within javascript so I can store it properly in the EBCDIC db?

Thanks!

If "all of the usual letters and symbols seem to automagically convert", then I very strongly suspect that you do not have to create an EBCDIC string in Javascript. The character codes for Latin letters and digits are completely different in EBCDIC than they are in Unicode, so something in your server code is already converting the strings.

Thus what you need to determine is how that process works, and specifically you need to find out how the translation maps character codes from Unicode source into the EBCDIC equivalents. Once you know that, you'll know what Unicode character to use in your Javascript code.

As a further note: every single time I've been told by an IT organization that their mainframe software requires that data be supplied in EBCDIC, that advice has been dead wrong. The fact that there's some external interface means that something in the pile of iron that makes up the mainframe and it's tentacles, something the IT people have forgotten about and probably couldn't find if they needed to, is already mapping "real world" character encodings like Unicode into EBCDIC. How does it work? Well, it may be impossible to figure out.

You might try whether this works: var notSign = "\u00AC";

edit: also: here's a good reference for HTML entities and Unicode glyphs: http://www.elizabethcastro.com/html/extras/entities.html The HTML/XML syntax uses decimal numbers for the character codes. For Javascript, you have to convert those to hex, and the notation in Javascript strings is "\u" followed by a 4-digit hex constant. (That reference isn't complete, but it's pretty easy to read and it's got lots of useful symbols.)
