Created attachment 1829251 [details] Video showing that Backspacing over emoji sequences removes the sequences partly - Fedora-Workstation-Live-x86_64-35-20210829.n.0.iso, installed in qemu-kvm, with all current updates - libreoffice-core-7.2.1.2-1.fc35.x86_64 - google-noto-emoji-color-fonts-20210716-1.fc36.noarch (updated package installed from rawhide, that makes no difference for the problem reported here though) See the attached video. These emoji have been written into LibreOffice Writer: ๐จโ๐ฉโ๐งโ๐ฆ๐ณ๏ธโ๐๐ณ๏ธโโง๏ธ๐ดโโ ๏ธ๐จ๐ญ๐ด๓ ง๓ ข๓ ฅ๓ ฎ๓ ง๓ ฟ๐ด๓ ง๓ ข๓ ณ๓ ฃ๓ ด๓ ฟ๐ด๓ ง๓ ข๓ ท๓ ฌ๓ ณ๓ ฟ๐ฆฎ๐โ๐ฆบ๐ฉโ๐ฆฝ Moving the cursor over them using the arrow-left and arrow-right keys works well, each arrow-key moves over a complete emoji and only one emoji. But when the cursor is just behind one of these emoji, typing Backspace deletes not the whole emoji (as it should!) but only part of the emoji sequence.
I presume this is the same as https://bugzilla.redhat.com/show_bug.cgi?id=1883217#c1 where libreoffice follows the model in https://unicode.org/reports/tr29/ of "the backspace key might delete by code point, while the delete key may delete an entire cluster" and the arrow and delete keys work on the full cluster while backspace chips away at it to remove components of it and that was done deliberately during the original implementation targeting CTL
