The old decodeBase64 implementation tried atob() first which returns garbled text for UTF-8 content (e.g., Chinese characters), and only fell back to correct UTF-8 decoding when atob() threw an exception (which it doesn't for valid base64). Changes: - Add encodeBase64/decodeBase64 utilities to web/src/lib/utils.ts using TextEncoder/TextDecoder for proper UTF-8 support - Update file.tsx to use shared decodeBase64 instead of buggy local impl - Update files.tsx to use shared encodeBase64 instead of deprecated escape/unescape approach
