Well said. Thank you for telling of these experiences. Now please,=20
let=E2=80=99s put the shoe on the other foot.
I ask everybody who wants an English-only mnemonic standard to entrust=20
*their own money* to their abilities to very, very carefully write this=20
down=E2=80=94then later, type it back in:

(Approximate translation: =E2=80=9CWhatever would you do if Bitcoin had be=

No, wait: That is only a 12-word mnemonic. We are probably talking=20
about a Trezor; so now, hey you there, stake the backup of your life=E2=80=

savings on your ability to handwrite *this*:

Ready to bet your money on *that* as a backup phrase in your own hands? =20
No? Then please, stop demanding that others risk *their* money on the=20
inverse case.
----
If you cheat here by having studied Japanese, then remember that many=20
Japanese people know English and other European languages, too. Then=20
think of how much money would be lost by your non-Japanese-literate=20
family and friends=E2=80=94if BIP 39 had only Japanese wordlists, and your =
folks=20
needed to wrestle with the above phrases as their =E2=80=9Cmnemonics=E2=80=
=9D.
In such cases, the phrases cannot be called =E2=80=9Cmnemonics=E2=80=9D at =
all. A=20
=E2=80=9Cmnemonic=E2=80=9D implies aid to memory. Gibberish in a wholly al=
ien writing=20
system is much worse even than transcribing pseudorandom hex strings. =20
The Japanese man in the quoted story, who wrote =E2=80=9Caneter=E2=80=9D fo=
r =E2=80=9Camateur=E2=80=9D,=20
was not dealing with a *mnemonic*: He was using the world=E2=80=99s most=
=20
inefficient means of making cryptic bitstrings *less* userfriendly.
----
I began this thread with a quite simple request: Is =E2=80=9C=E6=97=A5=E6=
=9C=AC=E8=AA=9E=E2=80=9D an=20
appropriate string for identifying the Japanese language to Japanese=20
users? And what of the other strings I posted for other languages?
I asked this as an implementer working on my own instance of the=20
greatest guard against vendor lock-in and stale software: Independent=20
implementations. =E2=80=94 I asked, because obviously, I myself do not sp=
eak=20
all these different languages; and I want to implement them all. *All.*
Some replies have been interesting in their own right; but thus far,=20
nobody has squarely addressed the substance of my question.
Most worrisome is that much of the discussion has veered into criticism=20
of multi-language support. I opened with a question about other=20
languages, and I am getting replies which raise a hue and cry of=20
=E2=80=9CEnglish only!=E2=80=9D
Though I am fluent and literate in English, I am uninterested in ever=20
implementing any standard of this nature which is artificially=20
restricted to English. I am fortunate; for as of this moment, we have a=20
standard called =E2=80=9CBIP 39=E2=80=9D which has seven non-English wordli=
sts, and four=20
more pending in open pull requests (#432, #442, #493, #621).
I request discussion of language identification strings appropriate for=20
use with that standard.
(P.S., I hope that my system did not mangle anything in the foregoing. =20
I have seen weird copypaste behaviour mess up decomposed characters. I=20
thought of this after I searched for and collected some visually=20
fascinating phrases; so I tried to normalize these to NFC... It should=20
go without saying, easyseed output the Japanese perfectly!)
