Hummm... so Lua should automatically be able to detect if the file is in 
EBCDIC encoding? (LF == 0x25)

How about handling UTF16 or UTF32 encodings? Should it automatically 
skip the BOM mark on those files? (tip; Windows apps tend to drop in the 
BOM on UTF8 encoded files, but not always)

At the least it should have support for the various local 8-bit code 
pages, yeah? Convert them to your preferred encoding.

Where do you propose drawing the line?

Ultimately, there is no such thing as a "text file", just a messy 
collection of conventions that may not hold, even within a single OS 
install. It's down to you, the programmer, to understand this and 
specify what is acceptable. It's not Lua's job.
