That's true, there are many ways to skin a cat, and how you read and  
process the file will very much depend on what you are trying to do.

The problem with this idea is that there is no standard way to determine  
the size of a text file. For some kinds of text 'file' (such as a device  
or pipe), it may not be possible to tell in advance by any means.

I think this is a terrible idea, unless you know what the character  
encoding is, and wish to do the decoding yourself!
