LabAnalyst can display a limited number of non-standard characters (i.e., characters that don't show on your keyboard but can be accessed with the 'option' key). These include:
° (as in °C or °F) -- shift-option 8 (option *)
• (bullet) -- option 8
π (pi) -- option p
µ (micro) -- option m
± (plus or minus) -- shift option = (option +)
≥ (greater than or equal to) -- option . (period)
≤ (less than or equal to) -- option , (comma)
∂ (derivative) -- option d
∫ (integral) -- option b
∆ (delta) -- option j
Use other such non-standard characters at your own risk -- they are likely to disappear or be converted into other characters when the comments, or files that contain them, are saved. These issues are due to the way non-standard characters are encoded.
