[jira] [Commented] (XERCESC-2101) Add support for XERCES_XMLCH_T = char16_t

JIRA xerces-c-dev@xml.apache.org

Roger Leigh commented on XERCESC-2101:
--------------------------------------

- [Unix build results|https://travis-ci.org/rleigh-codelibre/xerces-c/builds/242814234]
- [Windows build results|https://ci.appveyor.com/project/rleigh-codelibre/xerces-c/build/1.0.92]

All builds have passed using a mixture of old and new compilers using the previous defaults and char16_t, respectively.

Overall, this is a fairly trivial change to a typedef with the changes to the supporting build infrastructure to detect and enable it.  It enables the use of {{u"Unicode string"}}, which offers a significant usability improvement for end users of the library API, as well as a potential minor performance improvement by removing the need to transcode from 8-bit strings.  No need to transcode to wide strings for every element and attribute name, it's all handled at compile time by the compiler.
