Since the SI brochure does specify �C as the symbol for "degree
Celsius", I think that your first statement is entirely correct. Again,
the SI brochure is silent on the use of a space between number and unit.
Those that do and with which I am familiar do specify that space
*except* for the symbols related to angles. So they also prefer 90� to
90 � while still calling for 20 �C.
