Hi Karl,

I have updated (e)upTeX to 1.24 in r50095 and now in TeX Live 2019.

But we have found that contains a serious bug related to making control sequences.
We tried some workaround but it was found not to be enough.

https://github.com/texjporg/uptex-base/issues/3 (in Japanese)
https://oku.edu.mie-u.ac.jp/tex/mod/forum/discuss.php?d=2638 (in Japanese)

I have fixed the bug by r51021, r51069, r51221.
The latest (e)upTeX 1.25 fixed the issue.

I'm very sorry but I wonder if it could be rebuilt and
distributed by TeX Live before TeX Live 2020.

Best regards,
