[ 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} was: ByteStringBuilder cannot append codepoints 0xD8xx (lonely surrogates).
