[jira] [Comment Edited] (XALANJ-2419) Astral characters written as
a pair of NCRs with the surrogate scalar values when using UTF-8

I even figured out how to install CVS on my Mac (who thought I'd ever have to go there), and now the Apache CVS server is refusing connections. Sigh...

> Key: XALANJ-2419
> URL: https://issues.apache.org/jira/browse/XALANJ-2419
> Project: XalanJ2
> Issue Type: Bug
> Components: Serialization
> Affects Versions: 2.7.1
> Reporter: Henri Sivonen
> Attachments: XALANJ-2419-fix.txt, XALANJ-2419-tests.txt
>
>
> org.apache.xml.serializer.ToStream contains the following code:
> else if (m_encodingInfo.isInEncoding(ch)) {
> // If the character is in the encoding, and
> // not in the normal ASCII range, we also
> // just leave it get added on to the clean characters
>
> }
> else {
> // This is a fallback plan, we should never get here
> // but if the character wasn't previously handled
> // (i.e. isn't in the encoding, etc.) then what
> // should we do? We choose to write out an entity
> writeOutCleanChars(chars, i, lastDirtyCharProcessed);
> writer.write("&#");
> writer.write(Integer.toString(ch));
> writer.write(';');
> lastDirtyCharProcessed = i;
> }
> This leads to the wrong (latter) if branch running for surrogates, because isInEncoding() for UTF-8 returns false for surrogates. It is always wrong (regardless of encoding) to escape a surrogate as an NCR.
> The practical effect of this bug is that any document with astral characters in it ends up in an ill-formed serialization and does not parse back using an XML parser.
