Opentype implementation

The use of this font is very targeted. The user never selects an Mdotbelow unicode code directly. They use a custom software keyboard where the ‘M’ and the ‘dotbelow’ are typed separately, so in the text there are 2 separate unicode code points. In the past I used CCMP to point all of the iterations to a common code for consistency.



Does the users environment does properly support OpenType (mark positioning). Then add some anchors to all your glyphs and If the codepoint is not used then you can script it.
