Accents in URIs cause incorrect warning "escaping malformed URI reference" #378
Description
Consider the following document (in UTF-8):
<!DOCTYPE html>
<html dir="ltr" xml:lang="en" lang="en">
<head>
<title>a</title>
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
</head>
<body>
<p><a href="http://example.com/é">foo</a></p>
</body>
</html>
When running /usr/local/bin/tidy -utf8 -errors -quiet on this document, I get the following warning:
line 8 column 6 - Warning: <a> escaping malformed URI reference
The warning only shows up when the href contains an accented character. This seems bogus to me, I don't think non-ASCII characters in href are disallowed. Further, validator.w3.org accepts the document. I think the warning shouldn't be emitted.
This may be related to #352, but maybe not.
