Difference between ＆and & Character Encoding

I am building a CAML query and some of my values have

"＆" which translates to "＆" in U2U CAML Builder

However when I try to match the items in 开发者_JAVA百科my list that have "&" it fails.

When I input "&" into the valeus it translates to "&"

What is the difference between "＆" and "&" and how in code (vb.net) should I account for the difference?

The character is Unicode U+0026 &​ ampersand (38decimal, HTML: & &), this is inherited from the same value in ASCII. Apart from this, Unicode also has the variants:

* U+FE60 ﹠​ small ampersand (HTML: ﹠ )
* U+FF06 ＆​ fullwidth ampersand (HTML: ＆ in block Halfwidth and Fullwidth Forms)
* U+214B ⅋​ inverted ampersand (HTML: ⅋ )

I had the same issue right now and after a little research, I found out, that SharePoint saves Taxonomy values with ampersand (&) as fullwidth ampersand (＆) (unicode). You can convert your search query values (&) with TaxonomyItem.NormalizeName() in fullwidth ampersand (＆) (see https://msdn.microsoft.com/en-us/library/microsoft.sharepoint.taxonomy.taxonomyitem.normalizename(v=office.14).aspx?cs-save-lang=1&cs-lang=vb#code-snippet-1) and vice versa with string.Normalize() (see Convert fullwidth to halfwidth)

A good article about SharePoint ampersands you can find here:

As others have pointed out, ＆ is the character FULLWIDTH AMPERSAND, whereas & is a just plain AMPERSAND. The Unicode database declares these characters to be compatible, which means that if you convert both ＆ and & into the NFKD normal form, you will end up with the same result (specifically, &). If you wish to treat ＆ and & as if they were the same character, perhaps you could find a function that converts your strings into NFKD.
