Additionally some code from the libc++ project has been used as a reference; libc++ is a part of the LLVM project.
The libutf project (https://github.com/cls/libutf) was used as an inspiration for some of the Unicode implementation bits within libostd and the gen_unicode program used to generate the necessary ctype tables, but all of the code was written from scratch; nevertheless, I would like to give some credit and thanks to the project here.
Additional thanks to Dale Weiler aka graphitemaster (reference code in the Neothyne project) and cppreference.com.
