I've created a small text file 'swd' with some of the UTF-8 lines in
question. On my Linux mobile phone (a Debian Linux) it gives:
purism(at)pureos:~$ LANG=de_DE.UTF-8 sort swd
A
A010STRUKTUR
A010STRUKTUR
A010STRUKTUR
A0150SUPRALEITER
ゲアハルト・A・リッター
ゲルハルト・A・リッター
チャールズ・A・ビアード
On my FreeBSD laptop the same file sorts as
guru(at)c720-r368166:~ $ LANG=de_DE.UTF-8 sort swd
A
ゲアハルト・A・リッター
ゲルハルト・A・リッター
チャールズ・A・ビアード
A010STRUKTUR
A010STRUKTUR
A010STRUKTUR
A0150SUPRALEITER
I'll check tomorrow with the admins of the remote server (a SuSE Linux).
Thanks for the hint.
