QUESTION
I need to be able to convert text and a specific font to svg path data, and happened to come across opentype.js and maker.js, independent of each other, seeing that maker.js uses opentype.js. When I use opentype.js by itself, it doesn't render the font path correctly... when I give it a fill it doesn't display it properly. When I use maker.js, it is significantly better, but still incorrect.
TO BE ABSOLUTELY CLEAR ON THE PROBLEM DESCRIPTION: I need a way to translate text with a given font to svg path data that is then "flattened" (any black overlaps are unioned and any elements that are inside of the unioned text that is white is kept - for instance look at the letter "P"... If I union it, it removes the white part inside of the "P", of which I need). At this point I don't care about the means... it just needs to be compatible with php (it can't use imagemagick or other 3rd party software ran from the terminal - like inkscape... I don't have access to run shell_exec() or exec()) or javascript
I have had many trashed attempts, so... Help very much appreciated!
---maker.js---
This is one attempt... running this snippet causes my browser to crash, but in its own file works fine.
Here is the result and the code:

is shown as having intersecting paths. If you look at the path data output of opentype.js for this glyph, it looks like this (formatted for reading convenience):

Install svgd
You can use svgd like any standard Python library.
