Search with foreign characters (Danish æ ø å) not working

Hi, I have discovered that I am not able to search for links using the Danish characters æ, ø, å.

These characters work fine when searching posts using the built in search field, but not when I am using the [link-library-search settings=1] shortcode (I am using the great Danish translation of the plugin).

I am also using the Relevanssi search plugin, but I don’t think this has anything to do with it (have tried disabling).

I would really like to know if anyone else experiences this or know what might cause it. The site I am building is private, but login is possible with this info:

username: testuser
password: userfortesting

URL: opskrifter.frugtformidlingen.dk (click ‘Links’ in the menu).

Hope someone can help, thanks!

I have the same problem. my website is Japanese website, the plugin does not support Japanese Kanji search (Kanji UTF-8). English word search is OK.
Who can resolve this problem?

Hi Jircas

I had some help in figuring this out, so see if this works for you. As far as I understood, it’s a security thing. In line 4064 of link-library.php (ver. 5.6.9) it states:

if (ctype_alpha($searchterm) == true)

which apparently causes the error. The guy who helped me out used mysql_escape_string as protection, adding on line 4054

$searchterms = explode(" ", mysql_escape_string($_GET['searchll']));

This seemed to fix the error in my case. Hope it works for you as well. Entire file is pasted here: http://pastebin.com/TYLwqu4f – hope this is good with the plugin author.

thank you, eshenh,

I just try to follow what you told above to modify that line, but it does not work.
now I comment out that line:
if (ctype_alpha($searchterm) == true)
everything is OK.
It may have some security things as you said. But I don’t truly understand the purpose the plugin author adds this line for.

Yeah, I’m not entirely sure what it does myself, but as far as I can see, it checks if the search term is alphabetical: ctype_alpha

I think, that if you comment out the line, you will allow for searches that contain non-alphabetical characters and that might be a security risk. Not sure if this is critical, though.

Yeah, I need search Japanese word, as well as alpha.
after I remove that line, It can finish this job.
