 |
|
hi all,
having some problem with locale. I use an std::string, but seems like not
locale aware åäö = garbage. How do I make the string aware of my
scandi-locale? TIA

How will it behave differently once it's "locale aware"?

it will support åäöÅÄÖ, which it fails to handle right now.

You mean, you can't insert such a sequence into a string?
Bet you can. Of course, whether each of those glyphs shown
above is represented as one or more elements of the string
depends on a whole bunch of factors. But you still haven't
defined what you mean by "support."

What do you mean by "fails to handle"? I'm sure that if you have this code:
std::string s("æøå");
for (size_t i = 0; i < s.size); ++i) std::cout << s[i] << ": " << int(s[i])
<< n;
You would find three ints outputted - giving you the decimal value of three
"scandinavian" characters.

Are you sure libxml2 is parsing correctly? Have you printed the
strings before placing them in a std::string?

I mean that using std::string for handling parsed contents from rss feeds
doesn't work. The scandinavian characters are not represented/shown as they
should.

On what reason to you conclude it is not correct?
It is a common error to view such strings in the
console, a DB or a GUI system, and forgetting that
it is the console/DB/GUI system that behaves incorrect.

Produce an output-filter that translates the wrong codes to
the correct (Latin-1?) codes.
That's how I'm forced to do it for correct printing since BCB insists
on using a window charset instead of Latin-1 when compiling.

I checked teh output during parse, and it does not there either show åäö |
hmmm, now, the locale on my linux is sv_SV, seems to be correct,
I have also a problem with my webserver, when serving pages the same thing
happens on the client (windows), the documents åäö are gone, now this has
nothing to do with C++ but I'd be grateful if someone has ideas as hwo to
solve this problem as the two seem related.

Where are you outputting/displaying the strings? It's most probably an
issue with your environment, not std::string.
Make sure that the medium you use to display the text is aware of your
locale and that it uses a font which is able to render these characters.
For example, if you don't see the special characters on your console,
try installing transcoded font sets for X specific to your locale. This
is how I managed to display German Umlauts on a UNIX console.
