[DOC] PDF build has missing Unicode characters

Bug report

Bug description:

When compiling locally the PDFs (see https://github.com/python/docsbuild-scripts/issues/187#issuecomment-2373608230) for documentation a number of missing characters are reported.

howto-unicode.log:Missing character: There is no ♞ (U+265E) in font [FreeMono.otf]/OT:script=latn
howto-unicode.log:Missing character: There is no ♟ (U+265F) in font [FreeMono.otf]/OT:script=latn
howto-unicode.log:Missing character: There is no 😀 (U+1F600) in font [FreeMono.otf]/OT:script=lat
howto-unicode.log:Missing character: There is no 😉 (U+1F609) in font [FreeMono.otf]/OT:script=lat
library.log:Missing character: There is no ٤ (U+0664) in font [FreeMonoOblique.otf]/OT:scri
library.log:Missing character: There is no ௪ (U+0BEA) in font [FreeMonoOblique.otf]/OT:scri
library.log:Missing character: There is no ౪ (U+0C6A) in font [FreeMonoOblique.otf]/OT:scri
library.log:Missing character: There is no ໔ (U+0ED4) in font [FreeMonoOblique.otf]/OT:scri
tutorial.log:Missing character: There is no 景 (U+666F) in font [FreeMono.otf]/OT:script=latn
tutorial.log:Missing character: There is no 太 (U+592A) in font [FreeMono.otf]/OT:script=latn
tutorial.log:Missing character: There is no 郎 (U+90CE) in font [FreeMono.otf]/OT:script=latn

This means that the respective PDFs are missing the glyphs. The build was done using the French locale, but a previous build in English of the sole library.pdf reported a number of those already (those lines above from library.log).

CPython versions tested on:

3.13

Operating systems tested on:

macOS

Commencez par reproduire le build PDF dans les locales française et anglaise, puis examinez howto-unicode.log, library.log et tutorial.log pour rechercher les glyphes manquants signalés. Le travail est terminé lorsque les PDF concernés contiennent ces caractères et que le build ne signale plus les messages correspondants de caractères manquants.
