Arthur Sonzogni 8e98928c0c Support combining characters. (#121) ... Modify the ftxui::Pixel. Instead of storing a wchar, store a std::wstring. Now a single pixel can store multiple codepoints. If a codepoint is of size <=0, it will be appended to the previous pixel. Only ftxui::text() is supported. ftxui::vtext support still needs to be added. This causes the following CPU and memory regression: - Memory: Pixel size increases by 200% (16 byte => 48byte). - CPU: Draw/Second decrease by 62.5% (16k draw/s => 6k draw/s on 80x80) Both regressions are acceptable. There are still two orders of magnitude (100x) before the levels where performance/memory concerns begins. This fixes: https://github.com/ArthurSonzogni/FTXUI/issues/109		2021-06-26 01:32:27 +02:00
