I have documents with a lot of characters representing, for instance, an "e long" with an acute accent (an "e" with a dash over and an acute accent on top of the dash). It seems there are two ways to represent this type of characters with the hexadecimal notation:
1.- To use a simple hexadecimal if you have one, like ḗ in the case above.
2.- To use a composed hexadecimal: ē
Note that the second notation means the "e long" comes with a backwards character representing the acute accent.
So far so good...
But I have noticed that only the second solution works in Windows XP and only the first in Vista, son now I don't know how to deal with this characters so everybody can see them.
