Ligature
From DPCanadaWiki
To be created/developped and updated A ligature is one typographical character which combines two letters which are usually separate characters.
Here at DP, if the ligature is available in the UTF-8 character set, we usually proof it that way. For example, the "ae" and "oe" ligatures are normally proofed as the æ, Æ, œ, or Œ characters, as appropriate.
Most other ligatures are proofed as their component characters with no special markup, but if a particular ligature will be seen frequently in a given project, the PM will usually have addressed the issue specifically in the Project Comments.
For more information related specifically to æ and œ, including how to distinguish between the two in italics fonts, see Ae and oe ligatures.
