-Inja is a template engine for modern C++, loosely inspired by [jinja](http://jinja.pocoo.org) for python. It has an easy and yet powerful template syntax with all variables, loops, conditions, includes, callbacks, comments you need, nested and combined as you like. Inja uses the wonderful [json](https://github.com/nlohmann/json) library by nlohmann for data input and handling. Most importantly, *inja* needs only two header files, which is (nearly) as trivial as integration in C++ can get. Of course, everything is tested on all relevant compilers.

+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text
