I note that at least on my computer the CJK characters are wider than the ASCII characters, and thus makes columns not align. -- Richard Damon ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users

It works for me, using UTF-8 language settings for the terminal, and a font that contains enough of UTF-8. ~ $ uname -a Linux f7p3 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l GNU/Linux ~ $ set|grep -E '(LC_|LANG)' LANG=en_US.utf-8 LC_ALL= LC_COLLATE=en_US.utf-8 LC_CTYPE=en_US.utf-8 LC_MESSAGES=en_US.utf-8 LC_MONETARY=en_US.utf-8 LC_NUMERIC=en_US.utf-8 LC_TIME=en_US.utf-8 Column names used: e-acute and a-umlaut ~ $ sqlite3 test.db SQLite version 3.30.0 2019-09-25 18:44:49 Enter ".help" for usage hints. sqlite> CREATE TABLE x (é integer primary key,ä TEXT); sqlite> INSERT INTO x VALUES (1,'téxt'); sqlite> . mode column sqlite> . head on sqlite> select * FROM x; é ä -- -- 1 téxt sqlite>.q ~ $ sqlite3 test.db \ ".mode column" ".head on" ".width 1 4" "SELECT * FROM x" \ | hexdump -C c3 a9 20 20 c3 a4 20 20 20 0a 2d 20 20 2d 2d 2d |.. .. .- ---| 0010 2d 0a 31 20 20 74 c3 a9 78 74 0a|-.1 t..xt.| 001b -- Regards, Kees Nuyt ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
[sqlite] Hello everyone, I found some strange behavior when using the Command Line Shell For SQLite.
In column mode, each record is shown on a separate line with the data aligned in columns. For example: sqlite> .mode column sqlite> select * from tbl1; one two -- -- hello 10 goodbye 20 sqlite> But I found,only when columns text is ANSI,it can normal work. sqlite> .mode column sqlite> select * from 语言声明表; 语言指针 引用数量 语言名称 语言注释 -- -- -- -- 1 0 1 0 2 0 2 0 If the columns text is utf-8,it can't work. What should I do for it? ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
