'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.

Bug Fixes
Two Unicode characters were mapped to themselves.
pytooling.stydefinednewunicodecharmakes the character active, so each expansion re-inserted it: a document containing U+2264 or U+2265 ended inTeX capacity exceeded, sorry [input stack size=10000]instead of a PDF.

pyTooling/Actions, whose documentation contains U+2264 twelve times. Verified with MiKTeX 26.5 installed from this repository's own recipe: that document now builds to 275 pages.Related Issues and Pull-Requests
