The 3 i18n mistakes every open-source LMS makes

Short summary

Open-source LMS platforms commonly collapse three distinct i18n problems—UI strings, user-generated content, and canonical artifacts—into a single mechanism, causing bugs. The article analyzes Moodle, Open edX, Canvas LMS, and Chamilo, then proposes solutions: separate translation caches for dynamic content, layout testing in longer languages (Russian, German), and token-based canonical preservation to prevent auto-translation mangling. Practical fixes include switching Storybook to Russian by default and adding Playwright snapshot testing to catch localization regressions.

• •UI strings, user-generated content, and canonical artifacts each need separate i18n mechanisms—collapsing them is the root bug
• •Layout testing must occur in longer-content languages (Russian, German) to catch button/tab overflow before shipping
• •Token-based preservation prevents auto-translation from mangling canonical content like scripture or code samples
