FAQPage Schema
How do I fix unreadable Japanese characters and tofu glyphs in video thumbnails?

To fix unreadable Japanese characters and tofu glyphs in video thumbnails, standardize your visual assets on the Noto Sans JP font stack. This enforces consistent rendering and prevents platform fallbacks by requiring the font to load before rendering.

What is the recommended font weight hierarchy for Japanese subtitles?

The recommended font weight hierarchy for Japanese subtitles is 900 for display text, 700 for emphasis, and 400 for body text. This standardization maximizes legibility across different visual assets.

How to ensure consistent Japanese typography across UI components?

To ensure consistent Japanese typography across UI components, apply explicit typographic rules including prescribed line-height, letter-spacing, minimum size constraints, and a standardized Noto Sans JP font stack.

Do I need to install Noto Sans JP before rendering Japanese visual assets?

Yes, you need to install and ensure Noto Sans JP is loaded before rendering Japanese visual assets. This prerequisite prevents platform fallbacks and ensures the prescribed typographic rules apply correctly.

What are the limitations of using platform default fonts for Japanese typography?

Platform default fonts for Japanese typography often cause inconsistent rendering, unreadable text, and tofu glyphs across different environments. Standardizing on Noto Sans JP avoids these cross-platform visual inconsistencies.
