ToUpper()

[Ornette]

Hello,

I'm trying to convert strings to upper without the accents. For the moment,
ToUpper converts é to E with an accent...
I tried to set up english culture (en) but it's the same...

Any ideas ?

Ornette.

Ok, finally I did it like this :

private string ReplaceAccents( string chaine)
{

string strAccents=
"ÀÁÂÃÄÅàáâãäåÒÓ ÔÕÖØòóôõöøÈÉÊËè éêëÌÍÎÏìíîïÙÚÛÜ ùúûüÿÑñÇç";
string strNoAccents =
"AAAAAAaaaaaaOO OOOOooooooEEEEe eeeIIIIiiiiUUUU uuuuyNnCc";

char[] tAccent = strAccents.ToCh arArray();
char[] tNoAccent = strNoAccents .ToCharArray();

for(int i=0; i<strAccents.Le ngth; i++)
{
chaine = chaine.Replace( tAccent [i].ToString(), tNoAccent
[i].ToString());
}
return chaine;
}

J'ai pas trouvé mieux, même si ça boucle un peu pour rien...

Hello,

This is better :

byte[] bString =
System.Text.Enc oding.GetEncodi ng(1251).GetByt es(StringAvecAc cents);
string stringSansAccen t = System.Text.Enc oding.ASCII.Get String(bString );

string stringSansAccen t = System.Text.Enc oding.ASCII.Get String(bString );

Well, that's assuming that the encoding will find the closest match
letter. It may work now, but there's no guarantee that it will in the
future.

The mapping table idea you had before looked best to me, although I
wouldn't quite implement it the same way. I'd have a look up table for
every possible character, where it defaults to the Unicode character,
but for all the accented characters you care about, you specify the
non-accented version.

You'd then call ToCharArray() on the string in question, go through
each character replacing the original with the mapped character, and
then create a new string with the char array.

It does require you to manually map all the accented characters you
care about though.

My guess is that there are libraries around to do this somewhere, but I
don't know of any myself.

Ok, thank you for your point of view.
I really agree.

For the the librairies, I also didn't find any one.

Have a nice day and thanks again.

The closest thing that comes to mind is an RFC called stringprep. There are
a wide variety of stringprep profiles, and while they don't quite do what
you're looking for, they're close. Included in stringprep is a set of
mapping tables for Uppder->Lower case conversions. These are (in that
context) called case-foldings, are are found in table B.2. Unfortunatly,
they're Upper->Lower, not the other way around.

Stringprep:
http://www.faqs.org/rfcs/rfc3454.html

There are a number of profiles:
[Profile for Internaional Domain Names]
http://www.rfc-editor.org/rfc/rfc3491.txt

[Profile for iSCSI names]
http://tools.ietf.org/html/draft-iet...string-prep-01

[Profile for SASL UserNames & Passwords]
http://www.ietf.org/rfc/rfc4013.txt

[Profile for XMPP Resources]
http://www.xmpp.org/internet-drafts/...ceprep-02.html

There's a C# implementation of this RFC that's part of the libidn library.
There's also a C++ & Java version.
http://www.gnu.org/software/libidn/

We've actually got a full implemention of stringprep as well - it's much
more .Net 2.0 ish than the libidn one, which is just a native C++ app that
was then ported to Java & .Net. It's found in our open-source SoapBox
Framework.

In a more general way:

There is a Unicode database at

http://www.unicode.org/Public/UNIDATA/

You could do what you want in two steps: decompose the string to base
characters followed by accent (NFKD normalization), then remove the accents.

I hadn't thought of that, but it's certainly an option.

Doing the normalization in .Net 2.0 is easy enough:

string s = "test";
string normalized = s.Normalize(Nor malizationForm. FormKC);

Then you can iterate over the normalized string looking for (and
removing) the accents.
