It doesn’t currently, but that would be a fairly simple update to the code. Are you comfortable making changes? Feel free to contribute edits at https://github.com/nicjansma/rename-regex, or even just open an issue there as a feature request.

Is there any chance to make it go into folders recursively? Thanks

Hi — thanks for this. I noticed a small typo in this line: Rename files in the pattern of “124_xyz.txt” to “xyz_123.txt”:

Comment on MySQL: Converting an incorrect latin1 column to utf8 by Luca

Hi, very interesting article and thanks for explaining everything, from the look of it i thought i might have finally found the solution to my problem… but as it looks like i have different problem even if the description is exactly the same… in the end running the convert query i get the exact same result i get when selecting the original data… if i run it using a putty connection, if i run the conosle on my laptop, ssh to the server, and run the query i get the correct italian lettters i’m trying to put in the DB… (à é and so on) in BOTH columns… O_o

Thank you and.. “Any ideas?”

@Maryam
Maryam,

Are you using PHP on your website? Make sure you’re talking to the database in the right charset, for example:

mysql_set_charset(‘utf8′);

Does MySQL workbench report the colums as being utf8 now?

Hi,

Thanks for this very informational post although I have some problems that I can not fix with your guidelines.

The problem is that on our website we see invalid utf8 characters showing as �. I use MySQL workbench and if I select the column with the problem I also see a � as the query result.

So I though the script should fail on these columns. But the script never failed. then I though maybe I should get a list of all such values that are not valid as you suggested. So I ran this query:

mysql> SELECT MyID, MyColumn, CONVERT(MyColumn USING utf8)
FROM MyTable
WHERE CONVERT(MyColumn USING utf8) IS NULL
…

and it return 0 results.

Does this mean that the data is actually proper utf8? (conversion does not fail). if so, why is it showing as � in MySQL workbench when I view the value of that specific column?

Any help on this will be greatly appreciated. Once again thanks for sharing this with us.
