On this day in 2026, I am delighted to see that three languages with historical ties and close connections — CJK — are now available on Modrinth.

However, there are currently some issues regarding the glyph display across these languages, largely due to CJK Han Unification:

• https://en.wikipedia.org/wiki/CJK_characters
• https://en.wikipedia.org/wiki/Han_unification

Currently, the Modrinth website appears to hardcode lang="en" on the HTML document regardless of the selected language. As a result, browsers cannot properly apply regional glyph variants and must rely on the user's system font fallback.

For example, when a user switches the website language to Traditional Chinese, characters may still be rendered using mainland China (Simplified) glyph standards if their system font prioritizes mainland Chinese. Similarly, when a Japanese user switches to Japanese, certain Kanji are mistakenly rendered with Chinese glyph variants (or vice versa).

Describe the solution you'd like

To resolve this, updating the <html lang="..."> attribute to match the user’s active locale (e.g., zh-CN, zh-TW, ja, ko) would allow browsers to apply the correct regional fonts and display glyphs according to local conventions.
