Unicode input support

[googol4u]

Hi, Guys,

Thanks you for your great efforts to develop this tools. It makes remote management of databases possible.

However, some times we need to input Chinese to make some queries. It seems that henplus can not process Unicode characters correctly.

We use set-var to do the test.
Hen*Plus> set-var HELLO 你好

then we read the 'setting' file in .henplus folder, it turns out to be:

HELLO=\u00E4\u00BD\u00A0\u00E5\u00A5\u00BD

actually, there are two characters that we have just inputed. the correct setting should be:

HELLO=\u4f60\u597d

seems that the inputed unicode charaters have been converted into byte array.

Any work around for this issue?

Hi
I came across this issue like a couple of years ago and the workaround is in patching java readline library.
It is a dirty hack but this is what works for me:
