Daniel Kulp commented on CXF-3855:
----------------------------------
Actually, I think it should be escaped to %d8%61 to go into a URI? Right?
If I do:
{code}
String orig = new String(new byte[] {-47, -122}, "UTF-8");
orig = "/foo" + orig + ".txt";
String s = URIParserUtil.escapeChars(orig);
assertEquals(orig, new File(new URI("file:" + s)).
{code}
it fails as the URI doesn't decode properly with the old code or your code. If
I use %d8%61, it passes. Does anyone agree/disagree with that?
> Incorrect character escaping by URIParserUtil

> Key: CXF-3855
> URL: https://issues.apache.org/jira/browse/CXF-3855
> Project: CXF
> Issue Type: Bug
> Components: Tooling
> Affects Versions: 2.4.2
> Reporter: Jenya Pisarenko
> Priority: Minor
> Labels: parse, utf-8, util
>
> Class URIParserUtil. Function escapeChars(String s) produces incorrect result
> for characters, which utf-8 representation is greater than 1 byte length.
> For example, character "ц" ([-47, -122] in utf-8) is encoded as "%d861", but
> expected value is "%d186".
> This patch should fix the problem.
