Unicode JavaScript Source

[mcot]

It looks like it is valid to have unicode characters in JavaScript
source code, but the eval command is expecting a std::string it
seems. I got this error when trying to evaluate the code:

Python argument types in
JSContext.eval(JSContext, unicode, str)
did not match C++ signature:
eval(CContext {lvalue}, std::string source, std::string name='',
int line=-1, int col=-1, boost::python::api::object precompiled=None)

[mcot]

So here is what I mean about unicode in JavaScript source:

http://xahlee.org/js/ex/js_unicode.js

(This is part of a test page to see if your JS engine has unicode
support for var/function names).

OK, I have submitted a issue to follow up it

http://code.google.com/p/pyv8/issues/detail?id=75

[Flier Lu]

Now, PyV8 support to compile/execute the Unicode JavaScript Source,
and get/set Unicode attribute from both Python/JavaScript sides.

Please verify it with SVN trunk code after r341, Thanks

Hi mcot,

Could you try a clean build? I have moved Python::GIL to the
Utils.h/.cpp files, link the old .o files may cause issue.

No problems at all here.

I am still getting the same error even after a clean build.

OK, I will find a machine and try to reproduce it later

[Flier Lu]

I can't reproduce your issue at Ubuntu 10.04 x64, what's version of
your system, GCC and boost?

[mcot]

I installed boost via apt:

libboost-python1.40-dev seems to be the latest.

> Last Changed Author: fschnei...@chromium.org

[Flier Lu]

I think the boost version is not the root cause, did you modified some
files in pyv8? Could you check out the whole pyv8 project to a new
folder and try again?

Thanks

[mcot]

I built it on a fresh system and it worked fine. I am not sure what
was up with the old system.

Thanks for the help.
