[Dumu]: hello jedikaiti
[Dumu]: got it. Anyway. Perl question. Can you use binmode more than once with an open filehandle to read a file first in binary mode, then in utf8 mode?
[ambrus]: Dumu: you can use binmode multiple times, but mostly at the start before you read things. it would be strange to change the io layers after you've already read things, and might not work too well.
[ambrus]: Dumu: why would you want to read the same file both in binary mode and utf8 mode?
[Corion]: Dumu: Yes, but switching needs to be done with caution, as you might read half an UTF-8 character in binary mode, and then switch to utf8 mode...
[Corion]: Personally, I would do the decoding of data in the program and not in the filehandle
[Corion]: ambrus: Maybe a record-based file where some data is strings encoded as utf8
