- Sound engine: cache filesystem probe results to avoid repeated file existence checks; add MA_SOUND_FLAG_DECODE for pre-decoded playback
- Level renderer: column-level frustum culling, compact visible chunk lists to skip empty iteration, lightweight second-pass render path, early-out for non-dirty chunks, scaled recheck period at high render distances
- Entity: cache shared_from_this() to reduce reference counting overhead in move() and checkInsideTiles()
- Level: skip checkLight() when tile light properties unchanged; enable entity locking on all platforms (not just Vita)
- LevelChunk: only rescan min height when the minimum column changes; defer lightGap processing
- LivingEntity: use raw pointer cast instead of dynamic_pointer_cast; cache friction tile lookup
- ServerPlayerGameMode: return whether block was destroyed to avoid redundant tile update packets
This commit introduces Arabic text shaping in the chat application by adding `ArabicShaping.cpp` and `ArabicShaping.h` for handling contextual forms and visual reordering.
The rendering logic in `ChatScreen.cpp` is updated to utilize this new functionality, adjusting cursor positions accordingly. Other UI components, including `UIControl_Base.cpp`, `UIControl_Label.cpp`, and `UIControl_SaveList.cpp`, are modified to ensure proper display of Arabic text.
Additionally, `Font.cpp` is enhanced with methods for efficient rendering of pre-shaped text.

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
On the dedicated server, hardcore death now persists XUID and IP bans to
banned-players.json and banned-ips.json via the Access system, and
disconnects the player. Bans survive server restarts. Client-hosted games
retain the existing in-memory XUID ban with force-save behavior.
- Add hardcore property to server.properties (forces Hard difficulty)
- Add LevelData::setHardcore() so loaded worlds respect the server config
- Add PlayerList::banPlayerForHardcoreDeath() with persistent XUID + IP bans
- Reject respawn requests server-side in hardcore mode
- Ensure server-side player ticks run without move packets (fixes
environmental damage not applying for some clients)
- Restore 0x8 hardcore bit on LoginPacket/RespawnPacket wire format so
the client-side death screen detects hardcore mode correctly
