CGraphicText, CGraphicFontTexture and CGraphicDib are the 40250 bodies verbatim; CGraphicTextInstance is verbatim except that its D3D draws become UI render commands (one image quad per glyph, Bar for cursor/underline). - platform/Win32Gdi.cpp: the GDI subset those files call, over vendored FreeType 2.13.3, following GDI's LOGFONT cell height, win metrics and gasp rules; system font lookup with substitute and CJK fallback faces - Win32Crt: MultiByteToWideChar / WideCharToMultiByte (UTF-8 and 1252 by hand, other code pages through iconv) - CGraphicImageTexture memory textures: glyph pages reach Godot as "mem:<id>@<revision>"; Metin2PythonHost.memory_texture + Canvas cache - Util.cpp code page / font face table, SetDefaultCodePage at boot, DefaultFont_* block, fnt resource type, GetMaxTextureWidth/Height - TextTag, StringCodec, Arabic, Vietnamese copied from 40250 - tests: port.text (Tahoma 12 metrics, alignment, CP949), port.app_loop and python_host_test.gd now check glyph quads instead of text commands Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# python_host_check —— 在 app 进程里把内嵌解释器起来并跑 system.py（docs/PORT-PLAN.md 批次 2P step 4）。
|
||
#
|
||
# 和 ctest 的 `port.python_launcher` 跑的是同一条序列，区别只有一个：那边是独立可执行文件，这边在
|
||
# Godot 进程里，由 GDScript 发起 —— step 4 要验的就是这个差别。2V0 把 C++ 模块注册上之前，
|
||
# 2V0-e 的玩法桩让 system.py 真正走到 prototype.RunApp()；
|
||
# 没设画布尺寸时 app.Create 没有设备，RunApp 捕获 CREATE_DEVICE 并给出原版提示；设了尺寸以后
|
||
# system.py 停在 app.Loop() 里，由 ui_update 逐帧推进（_run_app_loop）。
|
||
#
|
||
# 真机上通常没有 40250 的 Client/pack（APK 里只有 python27.zip），所以分两段：解释器 + 标准库这一段
|
||
# 不需要 pack，任何平台都跑；system.py 这一段需要 pack，没有就跳过并说清楚。
|
||
#
|
||
# 桌面：python_host_test.gd（--script）；真机：MT_TEST_MODE=python 从 client_main.gd 进来。
