MySQL转储和导入不保留编码？

Question

I am trying to copy a table from on MySQL database on a remote machine to another MySQL database on my local machine. I noticed that after importing the dump to my local machine, there were characters like ’ instead of single quotes.

I assumed this was an encoding issue, so I went into both databases and ran show create table posts , near the end of both, I saw CHARSET=utf8 . Also, I ran file -i on the dump file, both before and after scp ing it to my local machine, and they were both utf8.

However, when I import this file, I get this before:

  attendees—policy makers, 

and after:

  attendees—policy makers,

I am not sure why this is happening, everything is using utf8, what am I missing?

EDIT: I am using mysql Ver 14.12 Distrib 5.0.75, for debian-linux-gnu (x86_64) remotely, and mysql Ver 14.14 Distrib 5.5.25a, for osx10.7 (i386) locally.

On both systems you must check that your connection encoding is correct:

SHOW VARIABLES LIKE 'character_set_%'

Usually seeing characters like that is the result of double-encoding. Make sure you can match up the connection and client encoding to be exactly the same. There is a number of command line options that can facilitate this, or if you're using a driver or client, something in there can tweak it.
