Creating a new writing system on modern computers
I thought the conglangs group might be interest in this, as a reference for what you would need to do if you wanted to implement a new conscript. It's mostly a quick overview of all of the pieces, with lots of references to further information. It covers Unicode, UTF-8, creating fonts, briefly touches on advanced font and rendering support for cursive languages, embedding fonts in PDFs and web pages, entering Unicode codepoints in HTML, creating keyboards or input methods to type in a script directly, locales, and localization of software.
Hope this helps out anyone who wanted to try implementing a conscript on their computer, but didn't know where to start!
