From 9440974f66422d63b2ee6c6288e942ecabd6a521 Mon Sep 17 00:00:00 2001 From: ocornut Date: Fri, 25 Jun 2021 15:47:42 +0200 Subject: [PATCH] Fonts: Add U+FFFD ("replacement character") to default asian glyphs ranges. Remove SetFallbackChar() (amend 0ffd99d31).

(#4269) - Fonts: Use U+FF0E dot character to construct an ellipsis if U+002E '.' is not available. (#4269) +- Fonts: Add U+FFFD ("replacement character") to default asian glyphs ranges. (#4269) - Demo: Fixed requirement in 1.83 to link with imgui_demo.cpp if IMGUI_DISABLE_METRICS_WINDOW is not set. (#4171) Normally the right way to disable compiling the demo is to set IMGUI_DISABLE_DEMO_WINDOWS, but we want to avoid implying that the file is required. diff --git a/imgui.h b/imgui.h index 5596eb56..9eeabbe9 100644 --- a/imgui.h +++ b/imgui.h @@ -2708,9 +2708,9 @@ struct ImFont ImFontAtlas* ContainerAtlas; // 4-8 // out // // What we has been loaded into const ImFontConfig* ConfigData; // 4-8 // in // // Pointer within ContainerAtlas->ConfigData short ConfigDataCount; // 2 // in // ~ 1 // Number of ImFontConfig involved in creating this font.
