Looking at the invalid set of characters in your [Bronek Kozicki's] URL
 -- "< > : " / \ |" it becomes quite clear that the
logic behind these is that they are reserved tokens in the command shell. 
But, in fact, so is "question mark" or "asterisk."  
a) ':', '/', and '\' are seperators in a path (nothing to do with the command shell).
b) ? and * are /not/ reserved tokens in the command shell.  It is a continuing pain to Windows command line tools authors that the command shell does not expand wildcards - that has to be done by each individual tool.  Similary tokenizing arguments is not done by the command shell, but by each tool - and to make that even mildly possible, forbidding " in filenames makes that a lot easier.
I don't see the logic behind >, <, and |, but I wouldn't assume it is the command shell that forces that.
