    changing the meaning of the URL.  For example, you can't decode
    "/foo/%2f/bar" into "/foo///bar" because the number and contents of
    path components is different.  Non-reserved characters can be
-   changed, so "/foo/%78/bar" is safe to change to "/foo/x/bar".  Wget

    "*" is unsafe in shell context, etc.
