And once that works well, we can remove the old code and old fields. +** Implement Unicode-compliant display of "default-ignorable" characters +See the "Characters Ignored for Display" section of paragraph 5.21 in +the Unicode Standard for the details. + +The implementation would import the data from Unicode UCD file +DerivedCoreProperties.txt, and provide a minor mode that arranges for +the characters with the Default_Ignorable_Code_Point (DI) property to +be hidden on display. One way of implementing that could be via +glyphless-char-display-control; that one is global, but maybe there's +a way of making it buffer-local. Alternatively, this could be +implemented in C in the display engine. + +An additional aspect of this is the display of U+00AD SOFT HYPHEN as +invisible except at line boundaries. Note that this would need to +support hard (physical) newlines in the buffer as well as soft +wrapping of long lines under 'visual-line-mode'. The algorithm for +selecting the wrap point may also need be changed to break at the soft +hyphen. + ** FFI (foreign function interface) See eg https://lists.gnu.org/r/emacs-devel/2013-10/msg00246.html |
