[jboss-jira] [JBoss JIRA] (ELY-139) ByteStringBuilder.appendUtf8Raw() cannot append lonely surrogates
[
https://issues.jboss.org/browse/ELY-139?page=com.atlassian.jira.plugin.sy...
]
Jan Kalina updated ELY-139:
---------------------------
Description:
ByteStringBuilder cannot append codepoints 0xD8xx (lonely surrogates). It should -
StringBuilder.appendCodePoint() work with it.
(Problem is only with uncomplete/nonvalid unicode strings, so it is not critical
problem.)
Mentioned in: https://github.com/wildfly-security/wildfly-elytron/pull/101
*UPDATE:*
ByteStringBuilder encode surrogates correctly by RFC3629 (if we ignore they are prohibited
because they are reserved for UTF-16). Conversly StringBuilder and (char) operator encode
D800-D8FF bad as 3F.
Problem is only in appending into ByteStringBuilder constructed as:
{code:xml}
new ByteStringBuilder(new byte[]{});
{code}
