Unusual characters in links can lead to "missing character", even if the character has a glyph in the main font #8802
Description
echo "[[ı]]" | pandoc -f mediawiki --pdf-engine=xelatex -o bug.pdf
[WARNING] Missing character: There is no 𝚤 (U+1D6A4) (U+1D6A4) in font [lmroman10-regular]:mapping=
The double square brackets which is used for internal links in mediawiki format caused this. This is not U+1D6A5 character. It is LATIN SMALL LETTER DOTLESS I (U+0131). If I used a single square bracket, there is no problem but then it's the wrong syntax.
