The patch seems to make better results.

But I found other bugs about decodings of "~" escape.
"~~" and "~{!!~}" should be encoded and decoded as below.
    "~~" -> "~~~~" -> "~~"
    "~{!!~}" -> "~~{!!~~}" -> "~{!!~}"

In really they are encoded properly, but decoded in wrong way.
    (decode-coding-string (encode-coding-string "~~" 'hz) 'hz)
    => "~"
    (decode-coding-string (encode-coding-string "~{!!~}" 'hz) 'hz)
    => #("\x3000" 0 1 (charset chinese-gb2312))

These behaviors are not affected by the patch.
