Don't think this is quite what you are looking for - but several years ago, came across a website that offered something similar.
You downloaded a template from the website, that had the alphabet and a series of numbers and other keyboard symbols on it, with little 'boxes' underneath each letter. You printed this out, and then filled in the boxes with your own hand. This was then scanned again, and uploaded to the website. A few minutes later, you could download your own "font", created from your own handwriting.
We played around with it a bit. Had the font installed into Word, and typed up a few memos... It was quite freaky printing a document in your own handwriting... We had a good few laughs about pranking one of our stressed-out partners, by doing the same with
his handwriting, and then having "him send himself" a fax from the future - he wasn't very tech-savvy - it would have blown his mind!
It was fun as a novelty - but pretty useless. The 'font' could obviously only be 'read' by other Word users, if they too had your font installed on their system, otherwise Word would simply default to one of the standard ones...
Today, I get the same childish thrill when I convert my handwritten notes on my iPad to pdf-'text' - but then I'm immature like that.
It would of course help if I can remember the name of the website. But since I cannot - this has arguably been a complete waste of time... Good luck with your search!
