c++ - Attributes for UTF-8 characters -


ncurses can display characters attached attributes via chtypes, constructed or'ing single character attributes bitmasks thusly :

addch('a' | a_reverse);

however, after enabling utf-8 support, pushing multibyte character screen must done via addstr(char const*), , there no room attributes.

is there possibility of keeping attributes multibyte characters, or should keep track of them myself , use attron()/attroff() when needed ?

there 4 character types can used ncurses:

the char , chtype data came first, 8-bit encodings. wchar_t , cchar_t came later wide-characters. latter of each pair former combined video attributes , color.

ncurses differs x/open curses allowing multibyte characters added via waddstr (and waddch) interfaces. "ncursesw" library (the "ncurses" library 8-bit encodings).

wchar_t holds more bits char.

on linux, wchar_t (almost) synonymous unicode. not portable, ncurses uses wide-character functions convert wchar_t needed utf-8 — or whatever terminal using encoding. likewise, input waddstr may utf-8, ncurses uses corresponding multibyte-character functions converting application's locale-encoding wchar_t values.
