(This message is about Mason 1.)
I have a very complex application environment. Part of the compexity is
that it permits my users to set it up using CGI or mod_perl (or FastCGI,
but let's ignore that). In most cases, people use the application with a
charset encoding of UTF-8. With me so far?
In addition to the normal Mason components (ones that emit HTML), I have a
handful of components that are used in AJAX requests and return JSON. The
JSON is created using the JSON Perl module with the method to_json to
serialize a Perl data structure. The data that is encoded is a potentially
complex data structure that includes strings, arrays, whatever. The data
comes out of BerkeleyDB files that are created and managed by this same
application, so the round trip of the data into the database *should be*
isomorphic. It appears to be from the logging and simple testing I have
done. Regardless, this all works great, unless any of the strings are
UTF-8.
If a string contains UTF-8 data, that data appears to be correct while
processing (I can log it and it comes out as you would expect), and when I
generate the json with to_json it is also still correct. However, when the
data is sent to Apache via $m->out, it gets encoded into UTF-8 AGAIN (so
the UTF-8 characters become escaped ASCII effectively). But this ONLY
happens when $m->out sends the data out via mod_perl. When in CGI mode it
is perfect.
Again, I recognize that this is complex, and in order to really help me out
it would be good to have a simple test case, but there is very little that
is simple about this environment. I was hoping someone might have seen
this before and have a simple hint.
Meanwhile, I will continue to rip my hair out.
