The missing symbol is omega (symbol for ohms) – I’ll try printing it – Ω. It came out OK on my screen. If you want to know more, read up about UNICODE. (It is too big a subject to condense into a readable posting. :-) )

In a nutshell 192 printable characters are available without going into Unicode. The US keyboard gives direct access to 96 of them. The UK keyboard gives direct access to 97 (the £ symbol is used in the UK quite a bit) of them (98 if you include the € symbol). When you use codes such as Alt0181, you are tapping into one of the characters that are not directly available from the keyboard. If you look at the Microsoft WORD package and execute the Insert->Symbol function, you can see all the encodings. _____ From: [email protected] [mailto:[email protected]] On Behalf Of Bill Hooper Sent: 06 March 2010 02:10 To: U.S. Metric Association Subject: [USMA:46859] special symbols (was degrees symbol On Mar 5 , at 6:05 PM, Pierre Abbat wrote: On Friday 05 March 2010 17:36:29 Bill Hooper wrote: ... the same codes for various special characters ... like ... the SI prefix micro-, l.c. mu (µ), The mu is not actually a mu (μ), ... but a micro sign (µ), I find it difficult to comprehend the statement that "the mu is not actually a mu (µ)". If it looks like a mu it's a mu. They may come in different styles (like italics, bold face, different type faces, etc.) but they are all mu's. I note that GCPM specifies that SI symbols are written in upright type (NOT italics) but I don't know the method of producing the mu in upright; I have to use italics or nothing. But it's still a mu, at least. Furthermore, calling it the micro- sign is circular reasoning. The symbol for micro- is DEFINED as the Greek lower case mu. Yes, it is therefore the micro- symbol (by definition) but it is nevertheless still a mu.
