This then defines a command  \xspace ,
which you use can as follows:

Please do *not* define single-letter commands for your own
macros. There are many with already have a meaning in TeX,
or (La)TeX with system-wide packages loaded for supporting
particular accents, languages and character sets.
  \B  \C  \G  \H  \L  \M  \O  \P  \S  \T  \U 
and maybe some others.
Even more of the lowercase ones have a meaning.

Why does this matter?
Think about collaborating with a foreign author,
or just requiring to typeset an author's name, affiliation
or foreign title, within a bibliography entry.

Using  \NN  is better, in that the name conveys the
"double-struck" aspect of the symbol that you want it for.

However, you still need to be careful of \AA  and  \SS
and maybe some others.
