I always thought this was such a cool idea to preserve the handwriting style of someone you love (I adore my partner's handwriting), but the conversion to a font never seems to keep the spacing right, as you show in the final comparison.

I've been thinking of tinkering with an image to image generation model to convert text output from the font into something that looks closer to the handwritten version. Seems like it should be possible, but you need a lot of data.
