Root cause
Translators accidentally delete closing braces or insert spaces inside printf specifiers (`% d`), and copy-pasting from Google Docs/Notion into Steamworks leaves raw ``/`` HTML or unclosed `[h2]`/`[list]` containers.
What TofuCheck does
Compares every target language cell against the source English placeholder signature, automatically repairs malformed `{0}`, `%s`, `%d`, and `

Rules a localization lead would write, enforced on every string.
Each check is a plain, inspectable rule — not a model's best guess.
Every codepoint against every cmap
Format 4 and Format 12 cmap subtables are parsed straight from your .ttf/.otf/.woff binary and intersected with every string in your .csv, .json and .po tables.
Tokens and tags survive translation
{player_name}, %s, {0} and [color] tags are diffed source-vs-locale so a translated variable key never ships as a runtime FormatException.
Loops that never click
WAV loop seams get a 64-sample cosine zero-crossing and an injected RIFF smpl chunk, so engines keep the loop points on re-import.
Code level determinism when you need it. Browser simplicity when you do not.
Same font, same strings, same report — every time. No AI guessing at your glyph coverage, and nothing leaves your machine.
What it costs compared to the usual options.
One-time passes, no seats to renew. Published list prices as of October 2026.

Questions we hear most.
Does TofuCheck upload our unreleased script or game assets to any server?
Never. The browser diagnostic and the Studio Pass run 100% locally using client-side parsing and the offline CLI. Dialogue CSVs, proprietary fonts and audio stems never leave your disk, so it is safe for NDA publisher builds.
How is this different from enabling pseudolocalization in Godot or Unity?
Pseudolocalization swaps ASCII for accented Latin (Ĥéłłô) to test string expansion. It cannot verify whether your bundled font files contain the CJK, Cyrillic, Hangul or symbol codepoints that are actually in your translated CSV or PO files.
Which engines and localization formats are supported?
UTF-8 CSV/TSV (Godot CSV, Unity Localization, I2 Localization), GNU gettext .po, flat or nested .json, paired with .ttf, .otf and .woff fonts and 16/24/32-bit PCM .wav files. Exports target Unity TextMeshPro, Unreal UMG and Godot 4.
What do I get with each pass?
Quick Fix Pass ($12): one project, full report and repaired exports. Studio Pass ($29): unlimited projects, offline build and the npx tofucheck CLI. Team & CI/CD Pack ($49): multi-seat license plus the GitHub Action gate for every pull request.
Will it tell me exactly which characters to add to my font asset?
Yes. Missing codepoints are listed per locale with row and key, and TofuCheck generates a TextMeshPro Custom Character Sequence and a Godot/Unreal glyph range file you can paste straight into your import settings.
Is there a refund policy?
Yes — 14-day unconditional refund if TofuCheck does not catch a single issue in your project. Checkout is handled by Lemon Squeezy.
