Special characters are encoded in the database, for site settings options

[alexvorn2]

If you change the name of the blog in the settings page, for example to "Donald's blog",
we can see in the mysql database, the result is "Donald's blog" for the blogname option name, so I can not understand why this happening, I think in the database the result should be the same of what we type.

All sensitization actions I think must be used on the front (page view) side not on the database side (before submitting to the database).

I use Windows 64b, PHP: 7.0.4, WordPress: 4.7.1
