Summary 0004183: Issue Parsing Querystring when it contains the url endcoded string '%A3'
Description We've come into an issue with the parsing of query string parameters and pinned it down to the handling of the encoded pound symbol '%A3'.

It looks like an IOException is being caught and logged, and any parameters after this are ignored.

The issue can be replicated by passing in the following string as a query to com.caucho.server.connection.Form.parseQueryString(..)

query = "cost=%a39.99"
Additional Information We're passing in UTF8 as the javaEncoding.

The exact error is happing around line 91 in

String value = converter.getConvertedString();

This goes into com.caucho.vfs.ByteToChar.getConvertedString() where the error is thrown when flush() is called.

Based on feedback, '%A3' is not valid UTF-8 encoding.

However, can the handling of the exception be done differently to allow the remaining valid characters to get parsed correctly?

E.g. "cost=%a39.99&storeId=12" would still parse the storeId.

Many thanks,
