The problem is indeed related to APR::Table, and is as follows:

APR::Table is a perl interface to the underlying C code in Apache.
The UTF8 flag (see perlunicode) which marks a string as being UTF8 encoded is internal to Perl
There is no space in the C code to store the flag

So you generate the string with the UTF8 flag set correctly, put it into APR::Table and it loses its flag. So when you retrieve it, you are receiving the individual bytes rather than the multibye character.

The solution to this is

 
    use Encode;
    my $bytes = get_data_from_APR_TABLE();
    my $characters = decode('utf8',$bytes);

This way, you reset the flag and all will be happy again.

The issue is that you need to know which strings are UTF8 before you decode them. I find it easier to make sure that everything that comes into my app all gets converted to UTF8, so I'm only ever dealing with one character set internally.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
