When a target language leaves the offer, the reason goes with it, so you never read a silent no.
The offer is a partition, not a list
Offered, removed with a reason, or not measured yet
The answer is three sets: targets offered, targets removed with the reason for each, and the rest, which were not measured. A removed target used to simply vanish, and the agent said it does not appear among the supported targets about languages nobody had measured. We corrected that: today a removal carries its reason.
Two questions, and silence means the opposite in each
A font that draws the letters, and knowing how to assemble the line
First: does a font exist that draws those letters? Second: do we know how to assemble the line? Right-to-left scripts must be reordered, and several South and Southeast Asian scripts shape each letter by context.
A missing font fails loudly: the original sentence stays on your page in the source language, the result is marked partial, and the receipt names what was left behind. So a target nobody has measured can still be offered: if it fails, you see it.
Missing assembly fails silently: every letter is drawn, the page looks finished, and only a reader of that script sees the line runs backward. So on this axis, unmeasured means unsupported, and the target is removed before it reaches you.
Where this bites: only in PDF
In office formats, the program that opens the file does the drawing; in PDF, we do
In office formats, the program that opens the file draws the line, so Arabic works in a presentation, a document and a spreadsheet. In PDF, translating means redrawing, and the drawing is ours.
Declared when you choose, not at delivery: Arabic is not offered as a PDF target, with the reason in the offer. Chinese, Japanese, Korean, Hindi and Thai are offered in PDF with a warning. A scanned page, an image rather than text, comes through flagged.
A language can also be missing because of the configured target list, an operating decision; the offer says which reason applies.
A warning without a size is not a warning
The same caveat once meant "a few passages" and "the whole document"
The rendering caveat named the scripts left out but not how much of the document that was. In a real case, a PDF translated to Japanese came back mostly in English under the same warning a nearly all-Latin document would get. Now, when the target is that script, the response says so in a field: all text translated for this target.
And today's state, dated. Translation stopped on 2026-08-23 when the provider credit ran out; the last complete translation job finished that day at 02:26 UTC. The credit was restored on 2026-09-30, and the next complete run will date this line. This page describes the capability and does not invite a live test until that run exists.
Limits per format: your documents. What not to do: trust. What stays in place: preserved layout.
