Will be fixed in LyX 2.5 and maybe the next release of LyX 2.4. You can fix it locally by replacing in the file unicodesymbols the line 0x200b "\\LyXZeroWidthSpace" "\\newcommand*\\LyXZeroWidthSpace{\\hspace{0pt}}" "force=utf8;utf8-cjk" "\\LyXZeroWidthSpace" "\\newcommand*\\LyXZeroWidthSpace{\\hspace{0pt}}" # ZERO WIDTH SPACE by 0x200b "\\LyXZeroWidthSpace" "lyxzerowidthspace" "force=utf8;utf8-cjk" "\\LyXZeroWidthSpace" "lyxzerowidthspace" # ZERO WIDTH SPACE -- Jürgen -- lyx-devel mailing list lyx-devel@lists.lyx.org https://lists.lyx.org/mailman/listinfo/lyx-devel
