Fonts with ligatures enabled by default, such as Calibri, Palatino Linotype, Adobe Jensen Pro, or Myriad Pro, can fail to export certain character sequences to PDF, EPS, SVG, and AI (Illustrator) formats. Some of the failed sequences include 'ff', 'fl', 'fi', and 'Th'. The characters may fail to appear in the export file, and text following the character sequence may appear garbled. For SVG export, the full export image may fail to render. This problem occurs on Windows XP when regional settings are set for non-English text input, and occurs on all versions of Windows Vista and Windows 7.
