for Switches ("non_ascii.ads") use ("-gnatiw", "-gnatW8");
from the gnat user guide, 4.3.1 Alphabetical List of All Switches:
`-gnati`c''
Identifier character set (`c' = 1/2/3/4/8/9/p/f/n/w). For details
of the possible selections for `c', see *note Character Set
Control: 4e.
This applies to identifiers in the source code
`-gnatW`e''
Wide character encoding method (`e'=n/h/u/s/e/8).
This applies to string and character literals.
> What's the way to manage Unicode correctly ?
There are two issues: Unicode in source code, that the compiler must
understand, and Unicode in strings, that your program must understand.
(I've never written a program that dealt with utf strings other than
file names).
-gnati8 tells the compiler that the source code uses utf-8 encoding.
-gnatW8 tells the compiler that string literals use utf-8 encoding.
package Ada.Strings.UTF_Encoding provides some facilities for dealing
with utf. It does _not_ provide walking a string by code point, which
would seem necessary.
We could be more helpful if you show what you are trying to do, you've
tried, and what errors you got.
