Commenting out the calls to unify-charset does reduce the memory by
several megabytes.
But I'm not sure I understand your idea correctly. Here's the approach
I tried, do you think it is correct?
- introduce a variable called inhibit-load-charsets-map, defaulting to
nil
- In loadup.el, let-bind inhibit-load-charsets-map to t when loading
characters.el.
- In map_charset_chars, when inhibit-load-charsets-map is non-nil, and
the charset method is deferred, don't call load_charset and
map_char_table_for_charset. Instead, call a new function
map_charset_chars_from_file.
- The new function map_charset_chars_from_file reads the code points and
character codes from the charset file and applies the function
argument passed to map_charset_chars on those codes directly.
Would this work?
