If you really want to use the DEGREE CELSIUS character          then copy and paste is OK  provided that your document is UTF-8 encoded and declared as such in HTTP headers  Using the character reference  amp  x2103  would work equally well  and would work independently of character encoding  but the source would be much less readable   The problem with Blackberry is most probably a font issue  I don   t know about fonts on Blackberry  but the font repertoire might be limited  There   s nothing you can do about this in HTML  but you can use CSS  possibly with  font face   But there is seldom any reason to use the DEGREE CELSIUS  It is a compatibility character  included in Unicode due to its use in East Asian writing  The Unicode Standard explicitly says in Chapter 15  section 15 2  page 497       In normal use  it is better to represent degrees Celsius      C    with a sequence of U 00B0 degree sign   U 0043 latin capital letter c  rather than U 2103 degree celsius      The degree sign          can be entered in many ways  including the entity reference   deg   but normally it is best to insert it as a character  via copy and paste or otherwise  On Windows  you can use Alt 0176   Caveat  Some browsers may treat the degree sign as allowing a line break after it even when no space intervenes  putting          and the following    C    on separate lines  There are different ways to prevent this  A simple and effective method is this   lt nobr gt 42   C lt  nobr gt
