问题
I'm retrieving photos info from Flickr into my site. For each photo, the URL, title, and tags are saved in MySQL database.
I read a lot about the most suited character set for such values and I found its mostly between using utf8 or latin1.
Some titles and tags include symbols like the copyright (or similar ones). Will I be OK with Latin1 character set?
回答1:
Never use utf-8 in your database if the stored text is 100% ascii. Bloating each character with utf-8 could imply a significant performance hit if the text is indexed.
回答2:
Always use utf-8, everywhere, in your database, text editor, html metas, charset headers....
This is the only advice I can give you.
