make the length of Japanese character is twice as English character exactly?

[Vincent Hou]

I have encounter a problem about the Japanese language ,

According to the customer's requirement, I have to make a good order for the character that they input, there will be the mixed English and Japanese characters in one line, so I should make them in a good order per their requirement, But in the browser, the length of 1 double byte character can't match 2 single byte character exactly, who can tell me which font-family can I use to achieve this purpose?
for example:

デ始
1234

there are 2 Japanese character, I want to the length is the same as the following "1234", each double byte character match 2 single character in browser.
So How can I do that? who can give me some suggestion on this? Thanks in advance!

On sorting to sort words or characters, I have experienced non English characters always precede the English ones and numbers.
Probably because of their value in the UTF charset.
Ordering is same as sorting and should be following the UTF-8 value sof those.
Also, it follows the dictiionary algorithm. if the first character is japanese, it will appear before numbers and English characters.

One thing I don't understand here is, why are you trying to order Strings by their size?

Thanks for your suggestion, the function I want to implement here is like a notepad , the users can input characters row by row what they want to , it can be mixed with English and Japanese , and for each row , it have a limitation,
for the layout problem , I have to make them in a good order ,the size of each Japanese character must twice as 1 English character, so that my content can be a good order. so is any other directions to me ? thanks!
