Of course this is the conservative stance where it is expected that people do not do silly things. But my guess is that it is much easier to handle. Is there a specific reason to pick normalization, apart from the obvious one? I see some similarities to tabs vs spaces for indentation here.
These are the obious reasons I can think of:
- It may not be easy for people to choose which normalization, or lack
of normalization is used by their preferred editor, or by their input
method. A piece of code not written by me can be in a normalization
state different from the one used by my editor, and to check it I must
examine the text at byte level, or use a tool, and it may be
impossible to establish with certainty.
- It's just crazy to not normalize the source text of a program, in
- Better: it's crazy to have unicode text not normalized to a known
form, in any application which does more than pass around the text
