[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

Beginne damit, den PDF-Build in den französischen und englischen Locales zu reproduzieren, und untersuche howto-unicode.log, library.log und tutorial.log auf die gemeldeten fehlenden Glyphen. Als erledigt gilt die Aufgabe, wenn die betroffenen PDFs diese Zeichen enthalten und der Build die entsprechenden Meldungen über fehlende Zeichen nicht mehr ausgibt.
