I’m exploring the Unicode Bidi Algorithm (UBA) and found the GNU FriBidi implementation of the UBA (in addition to Unicode’s own implementation). The Unicode implementation compiles quite easily with Visual Studio but GNU FriBidi requires MSYS and some code edits, as documented beautifully on kemovitra.blogspot.com. I know very little about Linux-based builds and usually have to resort to all sorts of edits to get some distros to build with Visual Studio but the excellent notes on kemovitra.blogspot.com worked perfectly, first time, so a huge thank you to the author of that blog post.
