Sharing a #Tamil #Wikipedia URL

When someone pastes to you the URL for the Tamil Wikipedia Village pump, it will likely look like one of these:

• http://ta.wikipedia.org/wiki/%E0%AE%B5%E0%AE%BF%E0%AE%95%E0%AF%8D%E0%AE%95%E0%AE%BF%E0%AE%AA%E0%AF%8D%E0%AE%AA%E0%AF%80%E0%AE%9F%E0%AE%BF%E0%AE%AF%E0%AE%BE:%E0%AE%86%E0%AE%B2%E0%AE%AE%E0%AE%B0%E0%AE%A4%E0%AF%8D%E0%AE%A4%E0%AE%9F%E0%AE%BF
• http://ta.wikipedia.org/wiki/விக்கிப்பீடியா:ஆலமரத்தடி
• http://tawp.in/r/262

The first option is copy pasting the URL directly. The second option is achieved by appending the name of the article after http://ta.wikipedia.org/wiki/ . The third option is courtesy of some clever JavaScript and a domain specially acquired for the purpose.

In a modern browser, the URL shows like the second option, it is sad that it reverts to gobbledygook when it is copy pasted. There must be a reason that once was valid, the question is if this reason is still valid.
