'less' is not a possibility (?) because some strings
are internal ones.
The specific problem is the following.
I have some strings in UTF-8, others in iso-8859
(obviously I know the charset of the strings).
Then I want to show them in a terminal. I need the
os charset because the strings have to be
converted into it to displaying purposes.
And obviously I want my program working
in several platforms with little trouble.
The problem perhaps is the not standardization of many
os (I have not used windows vista nor windows 7 nor mac)
in this regard.
In my old debian it returns
es_ES@euro (I am from Spain)
in windows xp it returns
No indication about charset (is it in this case iso-8859
However in a new ubuntu the response is
Therefore, can I admit that when no UTF-8 or UTF8 (with lowercase
varitions) appears then iso-8859 is a good assumption?
I believe that in the future all usual os will be standard (some kind
of UTF) in this and the present problem is gone.
