I couldn't see anything wrong with RGB's statement, but I frequently stumble over the terminology. This is especially true in column A of the Latin-1 Supplement [1], where the code-point and code-value seem to coincide. I've broken it down to make sure I understand [2]. I'd welcome any corrections or clarifications. Glyph: £ (pound sign) Unicode code-point, escape: \u00a3 UCS-4/UCS-32 code-value, hex: 0xa3 UTF-8 encoding, no BOM, hex octets: c2a3 Given the UTF-8 octet sequence for the UCS-4 range 0000 0080-0000 07FF, 110xxxxx 10xxxxxx -------- -------- c2 a3 = 11000010 10100011 10 100011 = 10100011 = a3 Mac users may like the desktop Calculator's "Programmer View", which conveniently displays ASCII or Unicode glyphs.

They don't then have to write a sandwich to run your code. For code to write/read a pound sign see http://mindprod.com/applet/fileio.html For the pound sign use '\u00a3'. If you use the character plain, it may get scrambled if your source code is not UTF-8 too. Recall that the console is likely not UTF-8, no displaying a result there will likely get scrambled. see http://mindprod.com/jgloss/encoding.html -- Roedy Green Canadian Mind Products http://mindprod.com There is no end to what can be accomplished if you don�t care who gets the credit. ~ Art Rennison

Many systems will accept further abbreviations too, e.g. "GBP 32.00" or "USD 1.5B", and I wouldn't expect drop-down currency lists to be used either, since entering a single field like those shown is faster than using a mouse to select from a currency list and then typing the amount. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |

You need the decimal place info for both validation and to expand abbreviations like 1.5M correctly. I'm intrigued to see that there are no longer any currencies with three decimal places. Some years back a few middle eastern currencies used them. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |
