Why did the size change from 255 to 191?
After a conversation on IRC with tcohen: A lot of fields are shrunk from 255 to 191. This is because index size for VARCHAR on InnoDB has a max size, in bytes, of 767 bytes (or similar) and utf8 uses 3 bytes for each char, and utf8mb4, 4. 767/3 > 255. but 767/4 > 191. https://dev.mysql.com/doc/refman/5.5/en/charset-unicode-conversion.html Gain functionality (necessary for true unicode), lose space (not an issue yet). -- You are receiving this mail because: You are watching all bug changes.
