I think my only concern with this and the other PR is the size of the test case. I would prefer if we could get in on A7 and adjust the font metrics until we had just a couple words and and absolute minimum of lines to exhibit the actual test subject. That makes it a lot easier to review both diffs of the debug file and the actual display PDF later when some minor metrics change affects things. These long lines on big pages add up to a lot of content to review hunting for the one syllable difference that may or may not matter.

I amended my test commit to make it smaller and on A7

Would that be sufficient?

• Line 1 and 3 show hyphenations in the segments resp. after and before the geminated L (to check replacement worked)
• Line 2 shows hyphenation at the segment with the geminated L (to check prebreak worked)
• Sequence repeated with the precomposed characters.

If I understand the test correctly the fixup commit I just sent should accomplish the same thing, save about 30 lines of diffs, and also be a lot easier to visually inspect later to see if the proper thing is still being tested. Can you give that a check to make sure I understood it correctly?

Looks good to me!
