Accent Insensitivity in Searches
Not only are Microsoft SharePoint Portal Server Search queries not sensitive to case; they are also not sensitive to accents when using either the FREETEXT or CONTAINS predicates. A search for the term "resume" also returns documents that contain "résumé". If an identifier or literal contains accented Unicode characters, the search query also matches entries that contain Unicode combined characters that use the base character of the accented character in the identifier or literal.
Note This is not the case for the character ranges 0x2e81-f8ff and 0x1100-0x11ff.
