I'm not trying to debate you guy.
I'm telling you that xn--nqv366b6vl.com does not translate to computers in the double byte format.
I went & typed in &
#35745;&
#31639;&
#22120;.com & it transfered to
http://xn--m7r387f65k.com
I do believe that the xn-- in the from means that the characters seem to be transfered to an assigned redirect set of numbers & letters. It possibly looks random.
One of the value that English dot coms have is the fact that the search engines pick up keywords.
I'm just saying that those combinations xn--m7r387f65k.com does not translate into computer.
I just type in something simple 日本.com it gives me xn--(another set of random numbers & letters)
It seems like these domains are assigned a xn-- & a random set of numbers & letters.
I'm not trying to say this to seem ignorant as you posted this to ask some questions. You yourself said that you don't speak Chinese, I don't either but I speak Japanese & understand a lot of problems with double byte languages.
I didn't realized that they assigned these native Chinese & Japanese characters to random numbers. Most of the developers I know in Tokyo don't buy these domain names anyway. This is just a fact.
There is no particular merit for the SEO keyword part of buying domains if it redirects to assigned random numbers & letters.
In my browser it would even better if it stayed 计算器.com but it doesn't it goes to xn--m7r387f65k.com. Is this your site?
My main point is this I have a perfect example.
Look at
http://www.dmoz.org/World/Chinese_Simplified/
& look at the link names & then actually click the links
The file names are native Chinese doublebyte
Browsers can't read it like the way it is. So it turns into longer URLs naturally.
This is most likely the reason why they assign xn-- & random numbers & letters.
If you say you don't speak Chinese, I really thought hey you just might not know. I'm not saying you're stupid or ignorant. It's a bit unjust dude to just assume that I'm ignorant. I've got some good feedback from people on this site & have consulted & developed for financial clients in Tokyo especially concerning the double byte compatibility issue. I thought I was just helping out.
