(read text between "```" in monospaced font) I opened a rectangle region with `C-x SPC`. I traversed left and down (i.e. the rectangle was started in the top-right corner). Then I replaced region and not all the occurrences were replaced. Only the occurrences between the starting and ending position of the cursor and inside the region. I replaced `]` by `+1]` as: ``` xx]xx**xx]xx ``` and the result was ``` xx]xx xx+1]xx xx]xx ``` where I would expect it to be ``` xx+1]xx xx+1]xx xx+1]xx ``` In GNU Emacs 28.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33, cairo version 1.17.6) of 2022-04-20 built on frederik Windowing system distributor 'The X.Org Foundation', version 11.0.12101003 System Description: Arch Linux Configured using: 'configure --sysconfdir=/etc --prefix=/usr --libexecdir=/usr/lib --localstatedir=/var --with-cairo --with-harfbuzz --with-modules --with-wide-int --with-x-toolkit=gtk3 --with-xft 'CFLAGS=-march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection -g -ffile-prefix-map=/build/emacs/src=/usr/src/debug -flto=auto' 'LDFLAGS=-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now -flto=auto'' Configured features: ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG JSON LCMS2 LIBOTF LIBSYSTEMD LIBXML2 M17N_FLT MODULES NOTIFY INOTIFY PDUMPER PNG RSVG SECCOMP SOUND THREADS TIFF TOOLKIT_SCROLL_BARS X11 XDBE XIM XPM GTK3 ZLIB Important settings: value of $LANG: en_US.UTF-8 locale-coding-system: utf-8-unix Major mode: C++//l Minor modes in effect: shell-dirtrack-mode: t smartparens-strict-mode: t smartparens-mode: t global-semantic-idle-scheduler-mode: t semantic-idle-scheduler-mode: t global-semanticdb-minor-mode: t semantic-mode: t delete-selection-mode: t global-display-line-numbers-mode: t display-line-numbers-mode: t tooltip-mode: t global-eldoc-mode: t show-paren-mode: t electric-indent-mode: t mouse-wheel-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t line-number-mode: t indent-tabs-mode: t transient-mark-mode: t abbrev-mode: t Load-path shadows: None found.
