UTF 8 Support

One of Nuklear significant features is UTF-8 support. For use it you may complete several steps:

1. Obtain font, which contain characters you may use.

2. Create glyph range table for your language. As example for Japanese (thanks to vaiorabbit):

   const nk_rune nk_font_japanese_glyph_ranges[] = { 0x0020, 0x00FF, 0x2200, 0x22FF, // Mathematical Operators 0x3000, 0x303F, // CJK Symbols and Punctuation 0x3040, 0x309F, // Hiragana 0x30A0, 0x30FF, // Katakana 0x0370, 0x03FF, // Greek and Coptic 0xFF00, 0xFFEF, // Halfwidth and Fullwidth Forms 0x4E00, 0x9FFF, // CJK Unified Ideographs 0};

Nuklear have some functions for creating glyph codepoint's by default:

• nk_font_chinese_glyph_ranges() for Chinese
• nk_font_cyrillic_glyph_ranges() for Cirillic
• nk_font_korean_glyph_ranges() for Korean

3. Create nk_font_config structure: struct nk_font_config config = nk_font_config(14); config.oversample_h = 1; config.oversample_v = 1;

4. Set glyph range table to config

• for built-in functions config.range = nk_font_cyrillic_glyph_ranges();
• for custom table config.range = &nk_font_japanese_glyph_ranges[0];

5. Load font with customized config nk_sdl_font_stash_begin(&atlas); struct nk_font *ubuntu = nk_font_atlas_add_from_file(atlas, "path_to_your_font", 14, &config); nk_sdl_font_stash_end(); nk_style_set_font(ctx, &ubuntu->handle);

Thats all! Now you can use UTF-8 encoding symbols in your's apps. if (nk_button_label(ctx, u8"Кнопка")) fprintf(stdout, "button pressed\n");
