hi Bart,

I have some questions:

Do you mean the charset of our webpage has nothing to do with the
encoding of the user's input?

can you give me some links resource for my reference/

i have tried your code,when i input:
ÖйúÓëÊÀ½çͬ²½

output in the next textarea:ÖÐ56fdÓë4e16½ç540c²½NaN

Thanks for your great work!

Please see below.

can you give me some links resource for my reference/

output in the next textarea: .....
Thanks for your great work!

The left textarea needs to hold an UTF-8 string representing GBK
characters. It is not the intention to paste Chinese characters into
the left textarea, since those are no valid UTF-8 encodings.

If a code point up to 127 is pasted, it is treated as ASCII. Any code
point from the 128-255 range must always be manifested in pairs, since
UTF-8 uses a two-byte encoding to represent characters of the GBK
table. Code points above 256 (as your Chinese input) may never be used
in the left textarea, as they cannot be a valid UTF-8 encoding. Please
refer to the specifications of UTF-8 to see how multibyte-sequences
are used to represent one character.

If these conditions are not met for the left textarea, then the input
is not valid GBK as represented under UTF-8, and the outcome of the
conversion on the right side will be unreliable.
