As you know, in my notes there are often mathematical expressions that involve Greek letters or special mathematical symbols - those that go beyond the ASCII character set. I am never sure just which of the ways to do that will work over the spectrum of browsers, operating systems, and installed "fonts" used by the members.
Below I will give some samples of different ways to include some of these characters. I'd appreciate it if some of you could report on how each of them "makes out" on your system (and of course, please describe the pertinent aspects of your system).
Greek letter lower-case mu:
• Code page 1252 ("Windows extended ASCII - western"): µ
• Unicode (Greek alphabet): μ
Greek letter lower-case lambda:
• Unicode (Greek alphabet): λ
Plus/minus sign:
• Code page 1252 ("Windows extended ASCII - western"): ±
• Unicode: ±
Degree sign:
• Code page 1252 ("Windows extended ASCII - western"): °
• Unicode [actually the same encoding]: °
Square root sign:
• Unicode: √
Almost equal sign
• Unicode: ≈
Multiplication sign (also properly used for "by", as when giving dimensions):
• Code page 1252 ("Windows extended ASCII - western"): ×
• Unicode [actually the same encoding]: ×
Thanks.
Best regards,
Doug
