How to convert to UTF-8

<< < (2/5) > >>

No, it's not always necessary but their content is a known cause of trouble in conversion, as well as a search index. Their content will also probably be useless after conversion. Emptying them will do no harm, as far as I know.

I examined the structure of [smf]_log_search files and only [smf]_log_search_subjects table contains a text field. [smf]_log_search_results table is also a known cause of trouble, although not containing a text field. I had seen the suggestion of emptying all log_search tables and I adopted it in guide.

I tried to gather the most common causes and give instructions that would not  affect useful data. I doubt that any guide can guarantee a successful conversion always but a more detailed guide is needed in instructions to prevent known causes of trouble, if possible, as also pointed by Illori.

As you are concerned about search, in this case all log_search tables were emptied

Thanks agridoc for your help!:)

Now, i'm not sure why would upgrade be a "must" here, i've done many conversations without upgrading first?

Hopefully it wouldn't be useless because as I wrote log_search_subjects is in the list of the tables converted, but since there is the possibility to recover the data it wouldn't be such a bit issue. Maybe you can add a note to do a "maintenance > repair boards" at the end of the procedure in order to restore all the search features. ;)

No, it's that I'm concerned by the fact that the tables are emptied, I'm more concerned by people going to open phpmyadmin! :P
I just suggested because I know many people are afraid by having to dig into the database and others are more prone to make disasters... :P

BTW, I'm not against it, I was just asking because of my inexperience in charsets conversions. ;)

There is a possibility that some mod might interfere with conversion process.

A Large upgrade is recommended to start with "clean" files. It's rather a cleanup. No real upgrade is necessary.

I also recommend default theme and English language to avoid possible errors from code in a custom theme or an error in language file.
