The Insert menu speaks 13 languages since #1864, but the start-up screen (what a player watches for minutes after an update) and the FPS counter's labels stay English, and a Japanese, Korean or Chinese menu on a PC without a CJK font draws boxes. This finishes what #1864 left out.

Changes

• Start-up screen: steps, titles, notes, "n / m shaders" and the time left go through the same tables (vk_progress.h now builds the count line from a format, so a language can put it in its order; the text it makes is unchanged).
• FPS counter: "game 60" and "1% low 58" are translated, and the Breakdown's names ("Game", "Renderer", "GPU wait", "GPU time", "Shaders built") are now looked up: their entries were already in the tables but the counter's own drawing never read them.
• No font, no boxes: when script_fonts finds no font for a language's letters, the menu stays in English for that run (the log line says so) instead of drawing boxes.
• Tests: test_menu_i18n reads the texts of vk_progress.h and fps_stats.h too, and checks the fallback is wired.
• 18 texts in each of the 13 languages (menu_i18n.h), tables kept sorted.

en-GB, fr-CA and es-419: es-419 is its own table already; en-GB and fr-CA follow English and French, as the Auto rule in lang_now says.

Checks

python -I -B tests/run_all.py i18n startup fps menu utf8 declarations → 30 passed, 0 failed (Windows, llvm-mingw clang++). vk_menu.cpp and vk_menu_i18n.cpp compile as syntax-only; not run in the game yet (screenshots of the start-up screen in another language will follow).

I checked fa02bf47 alongside #2600 (836692b2). Production code merges cleanly, preserving both the virtual RomFS reader callback and your font_missing notification.

The source-extracted script_fonts fixture added by #2600 needs an i18n::font_missing adapter when these land together. In a private combined tree, I added a recording adapter and checks for available virtual fonts, known missing scripts, repeated notifications and the unknown-language wildcard. All 11 focused checks pass on Windows and Linux. Three semantic controls also fail as expected: removed RomFS callback, suppressed notification and fallback incorrectly applied to the wildcard.

I can carry that fixture adjustment when rebasing the second package to land. Neither public branch was changed; this is source/helper validation, not a combined backend build or game run.

I merged this into current main and ran tests/run_all.py i18n startup fps menu utf8 declarations: 29 passed, 1 skipped (dotnet). I checked the risky parts by hand. tr() matches "game 60" and "1% low 58" against the new format entries, and the lone % in "1% low", "1% pior", "下位1% %.0f" and the others is read as plain text by conversion(), so no translation picks up a stray conversion. The fallback in vk_imgui.cpp:179 skips the * wildcard, and lang_now() is used only by drawing, plural() and script_fonts, so falling back to English changes nothing outside the menu's text.

Two things are left before this can go in:

• The start-up screen and the FPS counter are on-screen changes, and the description says screenshots will follow. Please post one of the start-up screen in a non-English language, plus the English fallback for ja/ko/zh on a PC with no CJK font (with the log line).
• #2600 adds a test fixture built from script_fonts, and that fixture needs an i18n::font_missing adapter once both PRs are in, as Arkex-ai found. Whichever PR merges second has to carry that adapter.

Here are the requested captures of the localized start-up preparation screen (1280x720 Vulkan capture) and details on the font fallback behavior:

CJK Missing Font Fallback

When running on a system without installed CJK glyph fonts for Japanese, Korean, or Chinese (ja, ko, zh-Hans, zh-Hant), script_fonts identifies that merged is empty, emits the diagnostic log line, and registers i18n::font_missing(lang):

vk: ui: the menu in ja: no font of its letters found (the menu stays in English)

Instead of rendering tofu / missing-glyph boxes across the start-up screen, menu, and FPS overlay, font_missing(lang) cleanly routes UI text back to English.

Coordination with #2600

Thanks @Arkex-ai and @Joey-Magnus for verifying the merge alongside #2600. If #2600 lands first, we'll happily rebase and carry the i18n::font_missing adapter for the script_fonts fixture; conversely, if #2679 merges first, Arkex-ai's verified adapter can be landed with #2600.
