让 MySQL 客户端命令行接受带重音符号的字符作为输入

Question

I don't know how to enable my MySQL client to accept letters with accents as input on the command line on Ubuntu. These chars are not echoed on the console nor accepted as input. As far as I remember, in previous versions of mysql, I solved this problem by launching the client with command mysql --default-character-set=utf8 but this doesn't work with mysql Ver 14.14 Distrib 5.7.25, for Linux (x86_64) using EditLine wrapper on Ubuntu 18.04.

What does work is echo 'SELECT "é" AS letter' | mysql <dbname> echo 'SELECT "é" AS letter' | mysql <dbname> , which gives the correct output.

I suspect the EditLine wrapper to be guilty of this behaviour, but I don't know how to get rid of this unwanted feature.

Answer 1

I discovered today that I inherited in my current bash an alias from the setup of a previous installation:

alias mysql='mysql --default-character-set=utf8'

Since I removed that alias (with unalias mysql ), the misbehaviour disappeared.

Answer 2

You can make your database support UTF-8 encoding

Try the following : ALTER DATABASE your_database_name CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Answer 3

如果您使用的是Terminal ，

Terminal > Preferences > Encodings > UTF-8 Unicode
