Plugin unexpectedly deleted all created content types and custom fields

[GoogleCodeExporter]

My site is multilangual. I created a new post type, gаve it a name in english, 
but Menu name- in other language. When I activated content type, a message 
appear: "Invalid post type" and button "Back". When I hit "Back" button all my 
created custom post types and custom fields were deleted!

I can't reproduce this.  What were the exact names you used?

Post type: order
Menu name: "Онлайн заявка" in bulgarian language.

Thanks for the details.  "order" might be a reserved word since it is also a 
database command.  I found some other words that WordPress does not play nicely 
with.   E.g. trying to name your post-type "preview" caused weird problems, so 
I had to add some code to prevent restricted words.

Hi,

Just had the same issue... I spent a lot of time thinking about the structure 
of the website, built all the content types, fields. Then today I had the 
excellent idea to create a content type named "actualite". When submitting I 
had "Invalid content type" and a Back button. 
Clicked Back, every configuration informations (fields + content types) was 
erased.

ARE YOU SERIOUS ?

Sorry for the trouble.  I would kindly request you to keep sarcasm out of the 
bug-tracker.  My initial attempts to reproduce the problem have been 
unsuccessful, but I promise that once I can find the bug, I will patch it and 
update my unit tests so the issue does not occur again.  If you need an 
immediate fix, please contact me privately and I can send you a quote.

After some few investigations. The problem isn't because of the "post_type". 
This is because I filled "Actualité" in the menu name and apparently utf8 is 
not supported when you serialize the array before it is saved in db.

Thanks for sharing the additional info.  It's actually WP that serializes data: 
that's how it stores options, but you're right: that can cause trouble with UTF 
characters (e.g. see Issue #88 for related discussion).  Perhaps the 
CCTM::charset_decode_utf_8() function can help with the post-type name as it 
did in issue #88.

I worked to reproduce this on my dev server, and I cannot: I'm able to name my 
post-types using utf8 characters in both the post-type name and in the Menu 
name.  The post-type name replaces utf8 characters with "_", and the menu name 
saves normally.  See screenshot:

This might have something to do with the environment.  If someone can provide 
me access to a server where this issue is occurring I can reopen the ticket, 
but right now I can't fix it because I can't reproduce it.
