65e4c57d3a Only assume width 1 when wcwidth() returns -1 on non-OpenBSD platforms. 2016-04-29 12:47:15 +01:00

7abdfbe20e OpenBSD wcwidth() is sensible and complete so if it returns -1 it means 
that a character is not printable, so return to ignoring such
characters.

23fdbc9ea6 Loads of platforms appear to have old or broken Unicode character type 
information and are missing widths for relatively common Unicode
characters (so mbtowc() works, but wcwidth() fails). So if wcwidth()
returns -1, assume a width of 1 instead of ignoring the character.

b8a102d26f Handle wcwidth() and mbtowc() failures in better style and drop 
characters where we can't find the width (wcwidth() fails) on input, the
same as we drop invalid UTF-8. Suggested by schwarze@.

c5689a5a40 Long overdue change to the way we store cells in the grid: now, instead 
of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.

This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.

The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.

d6daf37df4 Tidy utf8.c a little: build table on first use, and make utf8_width take 
a u_int rather than splitting and then combining again in utf8_split.

c41673f3fa If we know the terminal outside tmux is not UTF-8, replace UTF-8 in 
error messages and whatnot with underscores the same as we do when we
draw UTF-8 characters as part of the screen.

69e0b8326a Support UTF-8 key bindings by expanding the key type from int to 
uint64_t and converting UTF-8 to Unicode on input and the reverse on
output. (This allows key bindings, there are still omissions - the
largest being that the various prompts do not accept UTF-8.)

e9b58d9de4 Update the internal wcwidth(3) table of tmux(1) to match the data 
in /usr/src/share/locale/ctype/en_US.UTF-8.src, with one single
exception:  Keep U+00AD SOFT HYPHEN at width 1 rather than moving
it to width 0, a tradition already observed in the old
https://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c .
While here, manually rebalance the btree for optimal lookup speed.
OK nicm@
