New issue 474 by uAle... at ...626...: JSON Encode created wrong unicode for  
none-printable ascii characters
http://code.google.com/p/gambas/issues/detail?id=474

1) Describe the problem.

When using none-printable ascii characters in a string or collection and  
convert them JSON.Encode, the conversion to unicode goes wrong (looks like  
invalid data).

See the following JSON.Encode output:
{"Hex-00": "\u00x0", "Hex-01": "\u00x0", "Hex-14": "\u00x1", "Hex-15": "\u00x1"}

It converts hex-00 to "\u00x0", this should have been "\u0000".
It converts hex-01 to "\u00x0", this should have been "\u0001".
It converts hex-14 to "\u00x1", this should have been "\u000E".
It converts hex-15 to "\u00x1", this should have been "\u000F".

The JSON.Decode works correctly with "\u0001", "\u000E", etc.

Only the "\u0000" gets lost during conversion with JSON.Decode, but i am  
not sure if that is as designed.

2) GIVE THE FOLLOWING INFORMATIONS (if they are appropriate):

Version: 3.4.2 & 3.5.0 tested (same result)
Revision: r1234 (if you use a development version)
Operating system: Linu
Distribution: Ubuntu 13.04
Architecture: x86_64
GUI component: QT3 / QT4 / GTK+
Desktop used: Gnome / KDE ...

3) Provide a little project that reproduces the bug or the crash.

See attached project.

4) If your project needs a database, try to provide it, or part of it.

5) Explain clearly how to reproduce the bug or the crash.

6) By doing that carefully, you have done 50% of the bug fix job!

IMPORTANT NOTE: if you encounter several different problems or bugs, (for
example, a bug in your project, and an interpreter crash while debugging
it), please create distinct issues!
