Goal: Allow players to type and display text in any language supported by Unicode, including Chinese, Japanese, Korean, Thai, Arabic, Korean, Hindi, and more. This covers all text surfaces: chat editor, chat messages, signs (in-world and editor), world name/seed, server address/port fields, and all Iggy Flash UI text fields. Multi-language support: Two complementary rendering systems were added to handle Unicode text across the entire client: 1. Iggy UI (Flash-based text fields): A new UIUnicodeBitmapFont class serves Java Minecraft's glyph page PNGs (glyph_00.png-glyph_FF.png) through Iggy's bitmap font provider API. Registered as the global fallback font with metrics matching the Mojangles bitmap font for correct baseline alignment. When the primary bitmap font lacks a glyph, it returns IGGY_GLYPH_INVALID and Iggy seamlessly falls back to the unicode bitmap font. 2. Legacy C++ Font renderer (chat editor, in-world signs): Revived the commented-out unicode glyph page system in Font.cpp. Characters not in the bitmap font texture are rendered from glyph page PNGs loaded on demand, with proper texture switching mid-string. 3. ChatScreen input: Removed the restrictive acceptableLetters filter so all printable Unicode characters are accepted in chat. Languages now supported for text input and rendering: - Japanese (Hiragana, Katakana, Kanji) - Chinese (Simplified and Traditional) - Korean (Hangul) - Thai - Arabic - Hindi (Devanagari) - Russian (Cyrillic) - already worked via bitmap font - Greek - already worked via bitmap font - Polish, Czech, Turkish (Extended Latin) - already worked via bitmap font - Armenian, Georgian, and other scripts covered by glyph pages Security fixes: - Fixed memset under-initialization of Font::charWidths (zeroed 460 bytes instead of 460*sizeof(int)=1840 bytes, leaving entries 115+ uninitialized) - pre-existing bug - Added bounds checks to all UIUnicodeBitmapFont callbacks to reject glyph IDs outside [0, 65535], preventing OOB array access - Added bounds check in Font::width() section-sign fallback path to prevent OOB read on charWidths[] with high codepoints - Blocked Unicode bidirectional override characters (U+202A-202E, U+2066-2069) in chat input to prevent message spoofing Memory leak fix: - Fixed SignTileEntity::load allocating wchar_t[256] with new[] on every sign load without freeing. Replaced with stack allocation. Debug logging: - Added [SIGN] prefixed logging for sign save/update operations - Added [CHAT] prefixed logging for chat send/receive operations Files changed: - UIUnicodeBitmapFont.h/.cpp (new) - Iggy bitmap font for glyph pages - UIBitmapFont.cpp - Return IGGY_GLYPH_INVALID for unknown chars - UIFontData.h/.cpp - Added hasGlyph() method - UIController.h/.cpp - Load and register unicode bitmap fallback font - UITTFFont.h/.cpp - Added registerAsDefaultFonts parameter - Font.h/.cpp - Revived unicode glyph page rendering system - ChatScreen.cpp - Accept all Unicode input, block bidi overrides - Gui.cpp - Chat display debug logging - ClientConnection.cpp - Sign update debug logging - SignTileEntity.cpp - Sign save logging, memory leak fix |
