: description:
: Fix and document display of glyphless characters.
:
: src/xdisp.c (set_cursor_from_row): Fix cursor positioning on
: zero-width characters.
: (syms_of_xdisp) <glyphless-char-display>: Doc fix.
: src/.gdbinit (pgx): Adapt to latest changes in `struct glyph'.
: src/w32term.c (x_draw_glyphless_glyph_string_foreground): Draw the
: box before drawing the glyphs inside it.
: src/dispextern.h (enum glyphless_display_method): Rename
: GLYPHLESS_DISPLAY_HEXA_CODE to GLYPHLESS_DISPLAY_HEX_CODE. All
: users changed.
: src/term.c (append_glyphless_glyph, produce_glyphless_glyph): Fix
: comments.
: (produce_glyphless_glyph): Enclose "U+nnnn" and "empty box"
: whitespace in "[]", to simulate a box. Don't use uninitialized
: variable `width'.
: lisp/international/characters.el (glyphless-char-display-control):
: Renamed from glyphless-char-control; all users changed. Doc fix.
: Signal an error if display method is not one of the recognized
: symbols.
: doc/emacs/rmail.texi (Rmail Coding): Characters with no fonts are not
: necessarily displayed as empty boxes.
: doc/emacs/mule.texi (Language Environments, Fontsets): Characters with no
: fonts are not necessarily displayed as empty boxes.
: doc/emacs/display.texi (Text Display): Document display of glyphless
: characters.
: doc/lispref/display.texi (Usual Display): Characters with no fonts are not
: necessarily displayed as empty boxes.
: etc/NEWS: Document display of glyphless characters.
I think there's some exception we have to add here for newline
characters, because they are treated as GLYPHLESS_DISPLAY_THIN_SPACE or
as GLYPHLESS_DISPLAY_EMPTY_BOX with a width of 1 space, but I am not
sure what the best way to do this would be. Maybe Eli has a good idea
of how this can be fixed?
