[Koha-devel] binmode in pler scripts for utf-8 support

[Sébastien Nadeau]

Hi,

Indeed, it's important to do so when utf8 encoded text is going to be written to a filehandle. For example, when extracting data from an utf8 database like MySQL and writing it to a file, or when reading from an utf8 encoded file.

" To mark FILEHANDLE as UTF-8, use :utf8  or :encoding(utf8) . :utf8  just marks the data as UTF-8 without further checking, while :encoding(utf8)  checks the data for actually being valid UTF-8. More details can be found in PerlIO::encoding. "

This quote from the binmode perldoc suggests that one must take good care about what is written to the filehandle when the ":uft8" layer is used. It it's not well formed uft-8, the result might end up in something unexpected.
