Twenty bare codes reaching further east than any other set

Kling AI declares 20 same-host alternates, all of them bare language codes. The set is the only one in this register that names Hindi or Filipino, and a twenty-first alternate for Chinese points at another host and is not counted. As of 2026-09-22.

Twenty codes counted, one declaration discardedTwenty bare codes are served from the host being read and are counted. A twenty-first alternate is declared for Chinese and resolves to a different domain, so the rule applied to every vendor here discards it, exactly as it discards the equivalent declaration elsewhere.Where does the declared alternate resolve?On the host being readCountedTwenty bare codes, reaching South andSoutheast Asia.On a separate domainRecorded, not countedOne Chinese alternate.

Inclusion rule. One vendor, one column, including the declaration the rule discards, so a reader can see what the count left out. Order. Counted parts first, then the discarded one, then the form.

1Where the set reaches that others do not

Beyond the European group this set names Filipino, Hindi, Indonesian, Malay, Thai and Vietnamese. Hindi and Filipino appear in no other declared set in the register, which makes this the only declared list addressing South Asia at all.

A marketing site tends to be a more honest map of where a company expects revenue than a feature page is, because translating pages costs money per market. Read that way, the set says the buyers are expected across South and Southeast Asia.

2Bare codes throughout, and what that leaves unsaid

Not one of the twenty carries a region subtag. Portuguese is declared as pt, Spanish as es, Chinese not at all on this host. So the set names twenty languages and no markets, which is the opposite choice from the vendor with the longest list here.

For Portuguese and Spanish that matters to a reader, because the variants differ audibly and the page cannot say which one it follows. The register prints the codes as written so the difference between naming a language and naming a market stays visible.

3The Chinese alternate the rule throws away

A twenty-first alternate is declared for Chinese and resolves to a separate domain. Under the rule used for every vendor, alternates pointing at another host belong to that host, so it does not enter the count.

One other vendor here declares a Chinese alternate the same way and loses it the same way. Recording the discard on both pages is the point: a rule that is only visible where it helps a vendor would not be a rule.
