IDNA

This plugin adds IDN support to WordPress, making it an IDNA application. An IDN is a domain name that contains non-ascii characters.

This plugin enables one to set the WordPress address (URL) to an IDN. (instead of the Punycode Representation)

Examples of an IDN:

• bücher.ch

• domæne.dk

• nörgler.com

• uddannelsesstøtte.dk

• müller.de

• räksmörgås.nu

• 画像.jp

“An IDNA-enabled application is able to convert between the internationalised

and ASCII representations of a domain name. It uses the ASCII form for DNS

lookups but can present the internationalised form to users who presumably

prefer to read and write domain names in non-ASCII scripts such as Arabic or

Hiragana. Applications that do not support IDNA will not be able to handle

domain names with non-ASCII characters, but will still be able to access such

In simple terms, this plugin allows one to set their blog url to an IDN.

If you are interested in seeing what the PUNYCODE version of your IDN is, here is an online conversion tool

As an example:

>

de

Currently, she would have to set the WP blog url, (General Settings menu) to

de, (which is the ascii representation

de) this would allow users using a IDN aware web browser to access

de

de).

It is more convenient for Frau Müller to use the actual IDN

de as the WP blog url setting (General Settings menu),

this plugin enables that functionality.

There are a few caveats with using this plugin, depending on what Browser, Operating

System and versions used, one can get unexpected results.

*

Firefox supports IDN’s but maintains a ‘whitelist’ of ‘safe’ domains.

eu are not white listed for safety reasons, so IDN’s on these

domains will display as Punycode. see bug:

There is an new (‘experimental’) Firefox add-on,

IDN Navbar, which

will enable all (whitelisted – Punycode) domains to display as IDN’s.

So, if using Firefox and this plugin you (and your visitors) may want to install that addon.

*

Depending on your language set up, site’s that contain non ‘native language’

characters will display as Punycode and not the IDN. More info

msdn blogs

msdn libs1

msdn libs2

* seem to display IDN’s for all domain’s fine. (untested)

Arbitrary section

WP plugins have a ‘stable tag’ requirement for distribution, however, at this

time, I consider this plugin to be Beta quality at best.

It is possible to lock your self out of the administrative section of your blog

NOTE make sure you are using an IDN capable web browser when enabling this plugin.

NOTE Unfortunely, Current Firefox versions display the Punycode version and

NOT the IDN. For more details, (and work around) see the ‘Other Notes’ Link

IE7/8, Safari, Opera10 all display the actual IDN, Firefox (and Chrome)

navigation bar’s display the IDN as Punycode. e. xn--)

There are some security issues with multi-byte chars and phishing, so this is

Mozilla’s current approach, this may change in the future, as some folks are not

happy about it.

Because this plugin effects how you access your site, installation is slightly more

involved than most plugins.

If you installing this plugin, I would recommend, if possible, that it is the

first thing you do on your blog, before you add any content, just in case

something goes wrong, this will minimize downtime.

NOTE If something goes wrong and you cant access the WP admin area after

changing your url, here are some instructions for

resetting your url
