### ✨ Overview

Windows 10 and 11 do not natively support full Unicode flag emojis (e.g. 🇻🇳 🇺🇸 🇯🇵 🇫🇷 🇩🇪). This repository provides a complete solution to patch your system and make flag emojis render properly across all applications.

No waiting for Microsoft updates. No half-measures. This is a full technical fix built with persistence, system-level understanding, and community support.

## 🌍 Emoji Picker, Unicode Version 17.0 — A Technical Discovery About the Emoji Flags Mod for Windows 10

### ✅ Recommended Installation Steps

This is a curious discovery: by installing the `Segoe.UI.Emoji.with.Twemoji.Flags.ttf` font, I was able to:

- Enjoy the Windows 11-style emoji picker  

- Fully display Unicode 17.0 emojis (🫨🫠🫷🫸)  

- Render colorful national flag emojis (🇻🇳🇺🇸🇯🇵)

---

### 🔹 Step 1: Follow the setup guide 🇬🇧 [English](./guides/windows.en.md)

### 🔹 Step 2: Install the font that supports national flag emojis

📁 Font: [`Segoe.UI.Emoji.with.Twemoji.Flags.ttf`](https://github.com/Chasmical/flag-emojis-for-windows)  

📁 Or download from: [`/fonts/`](https://github.com/tuannvbg/unicode-flags-for-windows/tree/main/fonts)

- ✅ Displays full-color flag emojis (e.g. 🇯🇵🇫🇷🇧🇷)  

- ✅ Works with the Windows emoji picker (`Win + .`)  

- 🧩 Combines Segoe UI Emoji v1.60 with Twemoji v16.0.1  

- 📌 This font complements the base font — it does not fully replace it

---

### 🔍 Technical Insight: Font Stacking to Expand Emoji Support

The `seguiemj_1_31_mod.ttf` font already supports flag emojis, but since it's based on the original Windows 10 font, the emoji visuals are outdated — not as polished as Fluent 3D in Windows 11.

→ That’s why I tried installing `Segoe.UI.Emoji.with.Twemoji.Flags.ttf` by Chasmical to:

- ✅ Retain full-color flag emojis  

- ✅ Enjoy Fluent-style emoji visuals from Windows 11 (based on Segoe UI Emoji v1.60)  

- ✅ Combine with `seguiemj_1_31_mod.ttf` to add Unicode 17.0 support (🫨🫠🫷🫸)

📌 Technical explanation:

- Chasmical’s font does not replace all emojis — it only adds 258 flag emojis from Twemoji v16.0.1  

- The rest of the emoji set remains from Segoe UI Emoji v1.60 — Fluent 3D 15.1 (Windows 11 23H2, dated 2024-06-25)  

- From Chasmical’s repo:

  > *“This font is based on Segoe UI Emoji v1.60 (3D Fluent 15.1; Win11 23H2; 2024-06-25) and contains 258 flags from the Twitter Color Emoji SVGinOT v16.0.1 (2025-04-14) compiled by quarrel.”*

🧠 By installing `seguiemj_1_31_mod.ttf` first, the system falls back to it for rendering Unicode 17.0 emojis that Chasmical’s font doesn’t include.  

→ This is a clever font-stacking strategy:  

- The first font supplies new Unicode glyphs  

- The second font provides Fluent visuals and flag support  

→ Result: Windows 10 renders emojis like Windows 11 — but even better, with Unicode 17.0 support.

### 📷 Browser Font Configuration for Flag Emoji Rendering

After installing `Segoe.UI.Emoji.with.Twemoji.Flags.ttf`, I configured my browser to ensure flag emojis render in full color.

✅ Tip: Use `'Noto Color Emoji'` instead of `'Segoe UI Emoji'` to avoid blue-tinted or missing flag emojis.

### 🧪 System Compatibility Table

| OS + Font Setup | Unicode 17.0 Emojis | Flag Emojis | Notes |

|------------------|----------------------|--------------|-------|

| Win10 + `seguiemj_1_31_mod.ttf` | ✅ | ✅ | Full emoji set but legacy visuals |

| Win10 + `seguiemj_1_31_mod.ttf` + Twemoji Flags | ✅ | ✅ | Full emoji set with Fluent visuals |

| Win11 + Twemoji Flags only | ❌ | ✅ | Flags only, lacks Unicode 17.0 support |

---

### 📢 Conclusion

✅ **Windows 10 can fully display national flag emojis and Unicode 17.0**,  

if fonts are installed in the correct order: **base font first**, **Twemoji Flags second**,  

and the browser is configured to use `'Noto Color Emoji'` to ensure proper flag rendering.
