in reply to File Input and Output

running this code: open(FILE, "data.txt"); #opens data.txt in read-mode while(<FILE>){ #reads line by line from FILE which is the filehandle for data.txt chomp; print "Saw $_ in data.txt\n"; #shows you what we have read } close FILE; #close the file. results in: # perl test1 syntax error at test1 line 5, near "<" syntax error at test1 line 5, near ">" Execution of test1 aborted due to compilation errors.

    root just forgot that you don't need to escape less-than and greater-than signs inside <CODE> tags. Obviously, it should read:
    while(<FILE>)

[Corion]: Yaerox: That's a somewhat hard problem. Encode solves the conversion part, but for guessing what encoding a file is in, that's the hard part
[Corion]: Yaerox: There is Encode::Guess, but that needs a limited set of inputs, and it also cannot handle multiple single-byte encodings
[Corion]: If you have a BOM, that's a really easy way to recognize UTF-8. Otherwise, you can try to decode a file from UTF-8, and if that works OK and doesn't crash, most likely the file was valid UTF-8
[Corion]: But as "ansi" (Latin-1?) is a single-byte encoding, any file is a valid ANSI file
