Notes

No data is sent to the server (i.e. everything is done in JavaScript).
Conversion from Unicode to other encodings such as Shift_JIS can be slow first time as it needs to initialize internal conversion tables.
Surrogate pairs in UTF-16 are supported. Try inserting \uD840\uDC0B in the second form.
Three-byte characters in EUC-JP are not supported.
