Re: simbolo […]

Tuttavia ti invito a valutare l’utilizzo di xspace. Io lo trovo comodo…

The xspace package provides a single command that looks at what
comes after it in the command stream, and decides whether to
insert a space to replace one “eaten” by the TeX command decoder.
The decision is based on what came after any space, not on whether
there was a space (which is unknowable): so if the next thing
proves to be punctuation, the chances are there was no space, but
if it’s a letter, there’s probably a need for space. This
technique is not perfect, but works in a large proportion of cases.

Marco.
