* **Unicode is Huge:** Modern Unicode covers thousands of characters across hundreds of scripts. No single font file is likely to contain every single glyph for every language. * **Font Size:** A font that tries to include every possible glyph would be enormous in file size, impacting application load times and memory. * **Script Coverage:** Different scripts have vastly different character sets (Latin, Cyrillic, Greek, Arabic, Hebrew, CJK, Indic scripts, Southeast Asian scripts, etc.). **Recommended Strategy: Use Comprehensive Fonts and Fallbacks** The best approach is to: 1. **Choose one or two high-quality, comprehensive fonts** that cover the majority of the scripts you need. 2. **Configure `egui` to use these fonts with fallbacks.** This way, if a character isn't found in the primary font, `egui` will try the next one. **Excellent Font Families for Broad Unicode Coverage:** These fonts are designed to cover a wide range of scripts and characters. You'll typically need to download them. 1. **Noto Sans (Google Fonts):** * **Why:** Developed by Google with the goal of "supporting all the world's languages." Noto fonts are excellent for covering a vast majority of Unicode characters across many scripts. They come in various styles (Sans, Serif, Mono, Emoji). * **Coverage:** Excellent for Latin, Cyrillic, Greek, Arabic, Hebrew, East Asian (CJK), Indic, Southeast Asian, and many other scripts. * **How to get:** Download from [Google Fonts](https://fonts.google.com/noto). You can download individual font families or the entire Noto collection. For your `egui` app, you'll likely want `NotoSans-Regular.ttf`. 2. **Arial Unicode MS (Microsoft):** * **Why:** Historically, this was a go-to font for broad Unicode coverage. However, licensing can be an issue if you're distributing it commercially. It's often pre-installed on Windows systems. * **Coverage:** Very good, but sometimes not as up-to-date or as meticulously designed as Noto for certain scripts. * **How to get:** Typically comes with Microsoft Office or Windows. Be mindful of licensing. 3. **Source Han Sans / Noto Sans CJK (Adobe/Google):** * **Why:** Specifically designed by Adobe and Google to cover Chinese, Japanese, and Korean (CJK) characters comprehensively. If CJK languages are particularly important for you, this is a great choice. It's essentially the CJK component of the Noto family. * **Coverage:** Excellent for Hanzi, Kanji, and Hangul. * **How to get:** Download from [Google Fonts](https://fonts.google.com/noto/specimen/Noto+Sans+CJK+JP) (search for Noto Sans CJK) or [Adobe Fonts](https://fonts.adobe.com/fonts/source-han-sans). **Example Implementation in `egui` (using Noto Sans):** Let's assume you download `NotoSans-Regular.ttf` and `NotoSansCJK-Regular.otf` (for CJK coverage). ```rust use eframe::egui; struct MyApp { // ... } impl MyApp { fn new(_cc: &eframe::CreationContext<'_>) -> Self { let mut fonts = egui::FontDefinitions::default(); // 1. Load a primary font (e.g., Noto Sans for general Latin, Cyrillic, etc.) fonts.font_data.insert( "noto_sans".to_owned(), // Make sure to adjust the path to where you've placed your font file egui::FontData::from_static(include_bytes!("../assets/fonts/NotoSans-Regular.ttf")), ); // 2. Load a specialized font for languages not well-covered by the primary (e.g., Noto Sans CJK) fonts.font_data.insert( "noto_sans_cjk".to_owned(), // Adjust path egui::FontData::from_static(include_bytes!("../assets/fonts/NotoSansCJK-Regular.otf")), ); // 3. Add more fonts if you have specific needs for other very distinct scripts // (e.g., a font for Indic scripts if Noto Sans isn't enough or you want a different style) // Define font families and fallbacks // Using FontFamily::Proportional is common for UI text. // The order matters: the first font is tried first. fonts .families .entry(egui::FontFamily::Proportional) .or_default() .insert(0, "noto_sans".to_owned()); // Primary: Noto Sans fonts .families .entry(egui::FontFamily::Proportional) .or_default() .insert(1, "noto_sans_cjk".to_owned()); // Fallback 1: Noto Sans CJK // Add more fallbacks here if you've loaded more fonts // For monospace text, you might want a different font fonts .families .entry(egui::FontFamily::Monospace) .or_default() .insert(0, "noto_sans".to_owned()); // Or a dedicated monospace font if available // Apply the font definitions _cc.egui_ctx.set_fonts(fonts); Self {} } } impl eframe::App for MyApp { fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) { egui::CentralPanel::default().show(ctx, |ui| { // Now display text from your list - egui will try to find glyphs ui.label("English: Hello World!");

Noto Sans supports some Hmong variants. If you need specific Hmong characters, you might need to research dedicated fonts. * **`ig-NG` (Igbo):** Noto Sans should cover this. * **`ga-IE` (Irish):** Covered by Latin. * **`mi-NZ` (Maori):** Covered by Latin. * **`lb-LU` (Luxembourgish):** Covered by Latin. * **`mg-MG` (Malagasy):** Covered by Latin. * **`mt-MT` (Maltese):** Covered by Latin. * **`sr-RS` (Serbian):** `NotoSans-Regular.ttf` covers Latin Serbian. For Cyrillic Serbian, `NotoSans-Regular.ttf` should also cover it, or you might add `NotoSans-Cyrillic.ttf` if you want to be explicit. * **`st-ZA` (Sesotho):** Covered by Latin. * **`sn-ZW` (Shona):** Covered by Latin. * **`sd-PK` (Sindhi):** This uses Arabic script. `NotoSansArabic-Regular.ttf` is needed. * **`si-LK` (Sinhala):** Uses Sinhala script. You'll need a font that supports this, like `NotoSansSinhala-Regular.ttf`. * **`so-SO` (Somali):** Covered by Latin. * **`su-ID` (Sundanese):** Uses Sundanese script. You'll need a font that supports this, like `NotoSansSundanese-Regular.ttf`. * **`sw-TZ` (Swahili):** Covered by Latin. * **`tg-TJ` (Tajik):** Uses Cyrillic script (primarily) or Persian script. `NotoSans-Regular.ttf` (for Cyrillic) and `NotoSansArabic-Regular.ttf` (for Persian) would be relevant. * **`xh-ZA` (Xhosa):** Covered by Latin. * **`yi` (Yiddish):** Uses Hebrew script. You'll need `NotoSansHebrew-Regular.ttf`. * **`yo-NG` (Yoruba):** Covered by Latin. * **`zu-ZA` (Zulu):** Covered by Latin. **Downloading the Fonts:** 1. Go to [Google Fonts](https://fonts.google.com/). 2. Search for "Noto Sans". Download the regular style (`.ttf`). 3. Search for "Noto Sans CJK". Download the regular style (`.otf` or `.ttc` - you might need to extract the `.ttf` files from the `.ttc` if your backend requires it, but `include_bytes` often works with `.ttc` too). 4. Search for specific scripts if needed: * "Noto Sans Arabic" * "Noto Sans Hebrew" * "Noto Sans Sinhala" * "Noto Sans Sundanese" Place these `.ttf` or `.otf` files in a directory within your project (e.g., `assets/fonts/`) and update the `include_bytes!` paths accordingly. https://fontmeme.com/fonts/download/202855/noto-sans.zip 24.04.26
