9 # FCGI does not use Perl's I/O layer. Therefore it does not honor
10 # setting STDOUT to ":utf8" with "binmode". Also FCGI starting with
11 # 0.69 implements proper handling for UTF-8 flagged strings -- namely
12 # by downgrading them into bytes. The combination of the two causes
13 # kivitendo's way of handling strings to go belly up (storing
14 # everything in Perl's internal encoding and using Perl's I/O layer
15 # for automatic conversion on output).
17 # This workaround monkeypatches FCGI's print routine so that all of
18 # its arguments safe for "$self" are encoded into UTF-8 before calling
19 # FCGI's original PRINT function.
21 # However, this must not be done if raw I/O is requested -- e.g. when
22 # sending out binary data. Fortunately that has been centralized via
23 # Locale's "with_raw_io" function which sets a variable indicating
24 # that current I/O operations should be raw.
