Virtual font fallback to OFM for pTeX about dvisvgm HOT 9 CLOSED

Great, thanks for the confirmation. Since the additions seem to work as expected, I'm closing the ticket for now. Feel free to open it again if you still find any issues.

Thank you for the information. Could you please provide all files required to perform the tests independently of the TeX Live sources? Currently, I can't reproduce the segmentation faults. dvisvgm just prints several warnings, e.g.

As a first step it would help to have all data available to test a single case that leads to a segfault.

If the following lines are comment out by #, the segfault will be reproduced.

Ok, thanks for the hint. I've fixed the cause of the segfaults.

from dvisvgm.

The latest changes add OFM support and the corresponding VF fallback mechanism.

Thank you for the update.
I imported the sources and tested.
The segfault was fixed, but I could not get the same result between w/ and w/o fallback.

Do you get any warning messages from dvisvgm? For my tests I needed to adapt your upjf.map because it doesn't specify font files for the fonts listed there. Thus, I got the warnings shown above.

I use these entries taken from texk/dvipdfm-x/tests/upjf.map and get correct conversion results with them:

upjf-r   UniJIS-UTF16-H  HaranoAjiMincho-Regular.otf
upjf-g   UniJIS-UTF16-H  HaranoAjiGothic-Regular.otf
upjv-r   UniJIS-UTF16-V  HaranoAjiMincho-Regular.otf
upjv-g   UniJIS-UTF16-V  HaranoAjiGothic-Regular.otf

from dvisvgm.

Thank you for your comment.
I got intended results by using the following entries in the map file upjf.map.

t-tk/texlive-source@27ac1f7

upjf-r   unicode  HaranoAjiMincho-Regular.otf
upjf-g   unicode  HaranoAjiGothic-Regular.otf
upjv-r   unicode  HaranoAjiMincho-Regular.otf
upjv-g   unicode  HaranoAjiGothic-Regular.otf

Thank you for your support.
