Hello Marquex,
Thanks a lot for the plugin, it's really useful.
I had a small issue when using non ascii chars ('é' etc). If I used one of those characters to name a sidebar, I could use the sidebar without problem, but couldn't delete it afterwards. The error message was 'There was not any sidebar called "cs-hélios" and it could not been deleted'. In my sv_options table, the name was correctly stored as hélios but the id was stored as cs-h%c3%a9lios.
I am using WP 3.2.1, custom sidebars 0.8.1, the twentyeleven theme, and it is currently running on a local xampp installation with an utf8_general_ci database for wordpress.
I am new to the whole thing, so thank you for your tolerance if I shouldn't report this here or so :)
Thanks!
