9892d80d6f Most of the utf8_data is fixed so simplify utf8_set to use a memcpy. 2016-05-27 22:57:27 +00:00

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@.

3db0d50df4 The private use area at U+E000 to U+F8FF is not very useful if it is
width 0, make it width 1 instead.

205d15e82d All these return values from utf8_* are confusing, use an enum. 2015-11-14 11:45:43 +00:00

f401791a56 Rename a variable in utf8_combine for consistency and use 0xfffd for
unknown Unicode.

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.

ac3b78a841 Support for UTF-8 mouse input (\033[1005h). This was added in xterm 262
and supports larger terminals than the older way.

If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the
same manner as the utf8 option.

With help and based on code from hsim at gmx.li.

1af09d6330 Try to reduce the UTF-8 mess.
Get rid of passing around u_char[4]s and define a struct utf8_data which has
character data, size (sequence length) and width. Move UTF-8 character
collection into two functions utf8_open/utf8_append in utf8.c which fill in
this struct and use these functions from input.c and the various functions in
screen-write.c.

Space for rather more data than is necessary for one UTF-8 sequence is in the
utf8_data struct because screen_write_copy is still nasty and needs to reinject
the character (after combining) into screen_write_cell.
