Ada and UTF-8

Ada and UTF-8

[skylendar]

An iso8859-1 ascii string can easily be converted into a Wide_String
with the function To_Wide_String().

But I need to retrieve the UTF-8 image of such a Wide_String, and I
don't know how to do that.

Example:

W : Wide_String := To_Wide_String("accented characters ������");

then

S : String := xxx(W);


so that S would contains : "accented characters ééààèè"

Thanx for your help

This should become available with more recent compilers.
Ada 2005 supports UTF-8 via ISO 10646.
Meanwhile you can find implementations of Wide_String to UTF-8 String
in the GNAT sources, in XML/Ada, and elsewhere.
There is also EAStrings and AdaCL.

 So far, I use an internal GNAT conversion routine. But I wanted a
standard way to to this conversion. I'm looking forward to switching
to ada 2005 when available.

Thanx again

http://www.dmitry-kazakov.de/ada/strings_edit.htm 

with Strings_Edit.UTF8.Handling;
use  Strings_Edit.UTF8.Handling;
...
S : String := To_UTF8 (W);
