How to install ICU with your application
dtSearch includes a self-contained version of ICU that you can distribute with your application, subject to the 
Unicode License. The easiest way to deploy ICU is to put these files in the same folder as the dtSearch Engine library and the icuconfig.xml file that is included with dtSearch.
Windows: install icuuc63.dll, icudt63.dll, icuin63.dll, and icuconfig.xml in the same folder as the dtSearch Engine dll.
Linux: install libicuuc.so.63.1, libicudata.so.63.1,libicui18n.so.63.1 and icuconfig.xml in the same folder as libdtsearch64.so.
macOS: install libicuuc.63.1.dylib, libicudata.63.1.dylib, libicui18n.63.1.dylib and icuconfig.xml in the same folder as libdtsearch64.dylib.
UWP: ICU is included with UWP so only the icuconfig.xml file is needed.
For other deployment options, see icuconfig.xml.
