Umlaut-Fix

Umlaut Probleme sind in R4.0 gelöst.

Achte auf die Spracheinstellung der jeweiligen Seite, sie sollte für Deutsch => “de” sein, dann klappt's auch mit den Umlauten.

Wird die Sprachdatei /lang/wakka.de.php mit dem Editor “kate” geöffnet, bearbeitet und gespeichert führt dies zu Umlautproblemen. Änderungen an den Spracheinstellungen sollten deswegen in DeinemTheme/lang/wakka.de.php gespeichert werden. Das Hochladen einer ungeöffneten /lang/wakka.de.php Datei in Dein Webverzeichnis sollte das Problem beheben.

Ok, here is a quick fix for the Umlaut Problem in the German version.

Use the right charset on the Header-Files of your template. Replace the charset=windows-1251 with charset=ISO-8859–1

That's it.

If you don't like to change it yourself,

download this, extract the Zip-File and replace the files (they are for the default-Theme). (updated version)

Sorry, Roland, but removing htmlspecialchars leads to XSS bug. It's very dangerous. Try ==<script>alert('hi')</script>==.

Correct setting of charset & locale, depending on your lang settings will be included in R4.

— Roman Ivanov

Ok, you're right, Roman. I see, that this is a security risk. Now, I tested only with the correct charset, and it works even fine :-) This htmlspecialchar-Thing I tried, before I tried to change the charset.

— Roland Gruen

Even (or especially?) with the right charset, there is another bug: The german “sz” – looking like that: ß – is identified as a capital. So every word with an ß in it is build as Link. Any solution?

— Roland Gruen

You can try to use right locale setting for German (it's placed in beginning of wakka.php). I think it'll be solution.

— Roman Ivanov

Nope, didn't work. I tried setlocale(LC_CTYPE,'de_DE'); and setlocale(LC_CTYPE,'de_DE.ISO8859–1');, both didn't work. :-(

— Roland Gruen

What ASCII-code has “sz”? I think that problem in define("UPPER","[A-Z\xc0-\xdf\xa8]"); and define("UPPERNUM","[0-9A-Z\xc0-\xdf\xa8]");.

— Roman Ivanov

sz is the unicode-sign no. 223.

— Roland Gruen

Wacko works with 8bit texts, not Unicode. 223 – it's ASCII code. It matches [\xc0-\xdf] regexp. You need to modify these regexps (UPPER & UPPERNUM). We'll include that in R4 =)

Can you help, btw?
What symbols from

http://ar.sky.ru/ce.html is Upper, and what is lower for german or all central-european languages?

— Roman Ivanov

I'll try to help:

Upper:
ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝ

Lower:
ßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ

I don't know:
×÷¸Þ¨þ

The I-don't-know-signs are special symbols, I think, so I know, that ×÷ are mathematic signs, standing vor multiplicate and divide. (hope the signs will by right displayed on your screen, if not, tell me please)

Ok, back to my problem. I don't know much about this programming-thing ;-), so it would be nice, if you could tell me exactly, what I have to change. At the moment, the beginning of my wakka.php looks like this:

define("UPPER","[A-Z\xc0-\xdf\xa8]");
define("UPPERNUM","[0-9A-Z\xc0-\xdf\xa8]");
define("LOWER","[a-z\xe0-\xff\xb8\/]");
define("ALPHA","[A-Za-z\xc0-\xff\xa8\xb8\_\-\/]");
define("ALPHANUM","[0-9A-Za-z\xc0-\xff\xa8\xb8\_\-\/]");
define("ALPHANUM_P","0-9A-Za-z\xc0-\xff\xa8\xb8\_\-\/");
setlocale(LC_CTYPE,'de_DE.ISO8859-1');

Thank you!

— Roland Gruen

So, for CE-languages, code will be:

define("UPPER","[A-Z\xc0-\xd6\xd8-\xdd]");
define("UPPERNUM","[0-9A-Z\xc0-\xd6\xd8-\xdd]");
define("LOWER","[a-z\xdf-\xf6\xf8-\xfd\xff\/]");
define("ALPHA","[A-Za-z\xc0-\xd6\xd8-\xdd\xdf-\xf6\xf8-\xfd\xff\_\-\/]");
define("ALPHANUM","[0-9A-Za-z\xc0-\xd6\xd8-\xdd\xdf-\xf6\xf8-\xfd\xff\_\-\/]");
define("ALPHANUM_P","0-9A-Za-z\xc0-\xd6\xd8-\xdd\xdf-\xf6\xf8-\xfd\xff\_\-\/");

— Roman Ivanov

Hey, it works! Thank you very much! :-)

— Roland Gruen

Hi. I'm also German but I couldn't get the Umlaute to work entirely.

Changing charset=windows-1251 to charset=ISO-8859–1 and changing setlocale(LC_CTYPE,'ru_RU.CP1251'); to setlocale(LC_CTYPE,'de_DE'); only allows me to use Umlaute in normal Text and in Links but not in other formatted Text like Headings. Changing charset=windows-1251 to charset=UTF-8 allows me to use Umlaute in normal Text and other formatted Text but not in Links.

Do Umlaute work for you in normal Text, formatted Text and in Links Roland???

— Cub Bi

I don't understand. Did you change defines like shown above?

— Roman Ivanov

Yes, I did. I changed all charset-definitions (in every PHP file which includes one) and setlocale() and the UPPER-, LOWER- etc. definitions in wakka.php like shown above.

But I can get Umlaute only to work in normal Text and (Links XOR other formatted Text like bold text).

Links including Umlaute work with charset=ISO-8859–1.

Other formatted Text including Umlaute works with charset=UTF-8.

— Cub Bi

Can you give me any links? To one AND/OR other version?

— Roman Ivanov

Sorry. Right now I only have one running in the intranet of the company I work for.

But I will install a publicly available one next week. So, for now it seems as I have to live with that fact. It's not such a big problem really as I use now charset=UTF-8 and it is quite easy to remember that new links don't have to contain Umlaute. And the rest works flawlessly...
