Specific custom surrounds can not be changed via cs

[pilgrimlyieu]

I've used char2nr("（") and char2nr("）") to check the code and add the following setting.

let g:surround_65288 = "（\r）"
let g:surround_65289 = "（\r）"

And I can use ys command to add the surroundings or use cs command to change builtin surroundings(like ( etc.) to my custom surroundings(like （).

However, I can not change my custom surroundings to other surroundings, which means I can not use cs（( to change contents like （aaa） to (aaa).

Furthermore, I've tried a test surrounding as following.

let g:surround_126 = "~\r~"

But this time I can use cs~" to change ~aaa~ to "aaa". So I think may be only some special characters(may be full-width characters) can not be changed.

By the way, I type （ using key maps Shift + 9 while ~ needs Shift as well so I think it may have nothing to do with key input.

Here's an related pr

Closed because I use my fork version pilgrimlyieu/vim-surround that applies #355 changes.
