'newunicodechar' makes a character active, so its replacement text is expanded
again. U+2264 and U+2265 replaced themselves:
\newunicodechar{≤}{\ensuremath{≤}} % \le
\newunicodechar{≥}{\ensuremath{≥}} % \ge
Each expansion re-inserts the active character, which ends in
"TeX capacity exceeded, sorry [input stack size=10000]". The trailing comments
name what was meant - '\le' and '\ge' - and they are used now.
The other 82 mappings are not affected: they replace the character with a
command ('\dots', '\leftarrow', ...) or wrap it in '\emoji', which typesets it
through '\emojifont' rather than re-reading it as an active character. MiKTeX's
own 'example/lualatex/document.tex' uses such icons and builds.
Found in a Sphinx PDF build of 'pyTooling/Actions', whose documentation
contains U+2264 twelve times.

newunicodecharmakes a character active, so its replacement text is read again. Two mappings replaced the character with itself:Every expansion re-inserts the active character, so a document containing one of them ends in
TeX capacity exceeded, sorry [input stack size=10000].Bug Fixes
pytooling.sty: U+2264 and U+2265 are mapped to\leand\ge, which the trailing comments already named. The other 82 mappings are unaffected - they replace the character with a command (\dots,\leftarrow, …) or wrap it in\emoji, which typesets it through\emojifontinstead of re-reading it as an active character;example/lualatex/document.texuses such icons and builds.Others
pyTooling/Actions, whose documentation contains U+2264 twelve times. That build currently fails earlier, in atabularytable, so this defect is the one after it.
