Andreas Krantz commented on XERCESC-2132:
-----------------------------------------
I assume there are some test cases using u"" for uint16_t. Those test fail when
building with wchar_t instead because there is no auto conversion from L"" to
u"" or U"".
Because of this a reinterpret cast to XMLCh is needed to make it work in any
case.
> cmake: Add the ability to force the specific XMLCh type to use

> Key: XERCESC-2132
> URL: https://issues.apache.org/jira/browse/XERCESC-2132
> Project: Xerces-C++
> Issue Type: Improvement
> Components: Build
> Affects Versions: 3.2.0
> Reporter: Roger Leigh
> Assignee: Roger Leigh
> Priority: Major
>
> Currently the CMake build default to a 16-bit integer type. It will use
> char16_t where available, and fall back to wchar_t on Windows when available.
> This means that old Visual Studio versions will use wchar_t while newer ones
> use char16_t, but there are cases where selection of a specific XMLCh type is
> desirable, to force the use of wchar_t e.g. for compatibility reasons.
>
> Add an option to select a specific XMLCh type, overriding the default checks
> and fallbacks.
>
> Also, check that the autotools build behaves the same way.
