Does using ASCII/Latin Charset speed up the database?

由 牧云@^-^@ 提交于 2019-12-05 17:35:03
It would seem that using the ASCII charset for most fields and then specify utf8 only for the fields that need it would reduce the amount of I/O the database must perform by 100%. Anyone know if this is true? Update: The above was not really my question. I should have said: use Latin for the default character set and then only specify utf8mb4 only for the fields that need it. The thinking being that: using 1 byte vs 2 bytes should improve I/O by 100%. Sorry for the confusion. @RickJames is right, you should not worry about saving space by choosing ASCII or utf8 over utf8mb4. utf8 and utf8mb4

How can I alter an indexed varchar(255) from utf8 to utf8mb4 and still stay under the 767 max key length?

由 时光毁灭记忆、已成空白 提交于 2019-12-04 04:37:23
问题 I have an mysql column that needs to support emoji, and that means converting a utf8 column into a utf8mb4. But my varchar(255) won't fit, so long as the column is indexed (not unique). How can I keep the index, and get the utf8mb4 collation? I've tried to just reduce the length to 191 but unfortunately some of my rows are longer and I get this error: #1406 - Data too long for column 'column_name' at row 33565 (which isn't terribly helpful since I don't have an auto-increment column and have

How to remove 4 byte utf-8 characters in Ruby?

由 自古美人都是妖i 提交于 2019-12-03 07:10:00
问题 Since MySQL's utf8 doesn't support 4 byte characters, I'm looking for a way to detect and eliminate any 4 byte utf8 characters from a string in Ruby. I understand that I can update my table to use utf8m4 but for a couple reasons that's not possible or the desired solution. Simply encoding the string to ASCII will remove these characters but will also remove all other non-ASCII characters, which is not good. 回答1: The following seems to work for me in Ruby 1.9.3: input.each_char.select{|c| c
