Interesting read. I remember having to implement Unicode support and RTL in a graphic library (based on some version of InkScape, if I am not mistaken) that was code page. I implemented it using Uniscribe. The article 'Uniscribe: The Missing Documentation & Examples' was of great help implementing it. However, when I had to implement fallback fonts (for when the standard font does not contain the character you want to display and you want to get it from a different font) I got stuck because I discovered that at time (around 2015/2016) it was not implemented because MicroSoft had replaced Uniscribe by something new. There is also something interesting about the cursor moving through a miked LTR RTL text. It jumps over a character, meaning that it goes through different location depending on whether you move forward or backwards through the text, where forwards means that the cursor moves backwards on the screen when going through a bit of RTL text.
