Some replies have been interesting in their own right; but thus far, nobody= has squarely addressed the substance of my question.

Most worrisome is that much of the discussion has veered into criticism of = multi-language support.=C2=A0 I opened with a question about other language= s, and I am getting replies which raise a hue and cry of =E2=80=9CEnglish o= nly!=E2=80=9D

Though I am fluent and literate in English, I am uninterested in ever imple= menting any standard of this nature which is artificially restricted to Eng= lish.=C2=A0 I am fortunate; for as of this moment, we have a standard calle= d =E2=80=9CBIP 39=E2=80=9D which has seven non-English wordlists, and four = more pending in open pull requests (#432, #442, #493, #621).

I request discussion of language identification strings appropriate for use= with that standard.

(P.S., I hope that my system did not mangle anything in the foregoing.=C2= =A0 I have seen weird copypaste behaviour mess up decomposed characters.=C2= =A0 I thought of this after I searched for and collected some visually fasc= inating phrases; so I tried to normalize these to NFC...=C2=A0 It should go= without saying, easyseed output the Japanese perfectly!)
