Benjamin Bentmann updated IO-166:
---------------------------------
Attachment: IO-166.patch
New patch to also address the following issues:
# URL decoding should use UTF-8
# URL decoding should be lenient
Rationale for 1. is to bring the method in sync with the behavior of the
decoding done by the JDK, i.e. the output from
{code:java}
URI url = new URI("file:/home/%C3%A4%C3%B6%C3%BC%C3%9F");
System.out.println(new File(url));
System.out.println(FileUtils.toFile(url.toURL()));
{code}
is currently
{noformat}
/home/äöüß
/home/äöü�
{noformat}
Rationale for 2. is to better work with invalid URLs returned by bad class
loaders. There are still enough class loader implementations out that will
return a URL like "file:/<snip>/%file.txt" when queried for a resource named
"%file.txt", i.e. the URL is not encoded at all and can as such potentially
include literal percent characters. Hence I believe it is preferable for the
method to simply pass such characters literally through instead of failing with
an exception.
