How Are Typographic Ligatures Handled?
Examples: English ligatures like æ, œ, and ™ (trademark symbol) are expanded to ae, oe, and TM.
A term containing a ligature is also expanded at query time. When you search for terms that may contain ligatures, you can therefore use the ligature or expanded form of the term. They lead to the same results: documents containing either form of the term.
Note: CES 7.0.6830+ (July 2014) The ™ symbol appears in its original form (not expanded) in search results titles.
