Default Use of symbols and special characters

Sometimes when attempting to use mathematical or scientific notation it's handy to use the conventional or proper notation (eg x² rather than x2). I hit upon this site http://www.alt-codes.net/ and used it for a while, then started to have problems when I transfered to a Windows 7 PC.

After a bit of searching around, I found these Wikipedia entries, which explains why the alt-code mapping has changed for codes above 127:

http://en.wikipedia.org/wiki/Code_page_858

Unfortunately, it seems to have left us with no alt codes for Pi, Integral sign, equals approximately and omega!

Alt-234 gives capital omega Ω
Alt-247 gives approx equals ≈

That's how I have generated the above.

√ Ω ∫ π ≈ #

you can always go the long way round and copy paste from Word or similar.

This is a great program that let's you assign special characters to a particular key-stroke. For instance I've got Ctrl-Alt-u and Ctrl-Alt-o set to µΩ respectively.

No I hadn't, but I have now. I keep my equipment set to UK keyboard (the old DOS codepage 437).

There is a problem with special symbols, some fonts don't display the correct one, best to spell them out... Ohms, mili etc.

I just use Windows Character Map - most of the ones you need are in the Verdana font.

Default Re: Use of symbols and special characters

Going slightly off-topic, Word has symbols for fractions of half, quarters and eighths, is there any way of finding symbols down to sixteenths or even thirtyseconds? I use Word to create drawings with dimensions in fractional inches. (Of items originally made in a world of Imperial Units before metric units took over).

At least in Word you can type them like 1/32 and then make the numerator superscript and the denominator subscript.

I THINK there's a way of actually drawing your own characters but such things are beyond me.

Joe,
You can do it that way, but it's a lot more keystrokes and ends up looking more 'spread out' than the fractions which are available as symbols, they are quite compact.

It is available in Windows 7 too (in Accessories, System Tools).

I agree that the method I mentioned is far from ideal but is an improvement on plain 1/62.

Things can be squashed up a bit by fiddling with the line spacing, see below.

It IS a lot of messing about but you could always make a file of the fractions you use and then cut and paste them as needed.

To reinforce my thoughts, if it can't be read in good old plain ASCII text the effort to get it pretty may backfire. It's a case of style over content.

Any "free" musical note symbols anywhere?
