[jira] Resolved: (XERCESC-1916) TranscodeFromStr fails with invalid
UTF8 encoded strings
[ https://issues.apache.org/jira/browse/XERCESC-1916?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alberto Massari resolved XERCESC-1916.
--------------------------------------
Assignee: Alberto Massari
Fix Version/s: 3.1.1
Resolution: Fixed
TranscodeToStr and TranscodeFromStr now throw an exception if the internal transcoder doesn't advance the cursor; instead, the transcodeTo and transcodeFrom method exposed by the transcoders must return "0 bytes processed" to allow for incremental conversions (it's up to the caller to add more data and call the method again)

> If you got an invalid encoded UTF-8-sequence, the TranscodeFromStr ends up by throwing a OutOfMemoryException and if you use XMLTranscoder::transcodeFrom() directly you'll somehow probably end up in a loop that never ends, 'cause it stops to consume/eat bytes. Shouldn't there be some "InvalidEncodingException" instead ?

> xercesc::TranscodeFromStr transcoder( reinterpret_cast<const XMLByte *>(string), size, "UTF8");
> // OutOfMemoryException
