HEBCI is a technique that allows a Web form handler to transparently detect the character set with which its data was encoded. By using carefully-chosen character references, the browser's encoding can be inferred. Thus, it is possible to guarantee that data is in a standard encoding without relying on (often unreliable) Web server/browser encoding interactions.
libintl-perl is a library that supports message translation for Perl, written in pure Perl (version 5.004 or better). A faster C version is also built and installed if the system fulfills all requirements. Its interface is a superset of the gettext family of functions in C, and it uses the same file formats as GNU gettext, making it possible to use all tools available for gettext itself and to seamlessly integrate internationalized Perl code into mixed-language projects.
