Re^6: Match full utf-8 characters

STDIN->can("getc") being defined means that you can call the method: STDIN->getc().

Sorry about giving you misleading information on the "mode" parameter of IO::Handle::fdopen. From my understanding of the documentation (For the documentation of the "open" method, see IO::File. ... If "IO::File::open" is given a mode that includes the ":" character, it passes all the three arguments to the three-argument "open" operator.), it should have worked.

I also tried moving binmode(STDIN, ':utf8') ... but that did not help.

That is because you don't use the STDIN file handle, but create another one with the UTF-8 decoding layer stripped. Try setting ":utf8" binmode on STDIN, then using calling STDIN->getc (or just getc, since STDIN is chosen by default) in a loop.

Okay, I'm starting to see what you're talking about now. For example, if I set `binmode($stdin, ':utf8');` to correspond with my construct of creating a new `IO::Handle`, it works. I'm also understanding `STDIN->getc()`, I think I was trying to use `STDIN->can("getc")` in its place before. It's all starting to make a little bit of sense to me now. They are doing the same thing, with almost the same code, only I can use the global(?) STDIN filehandle instead of creating a new one. I've removed the unnecessary creation of a new `IO::Handle` and `fdopen`, and am just using STDIN like you suggested. Everything is working like I wanted and is much cleaner now. Thanks!
