Author Names in PDF Metadata

When an author name is written into a PDF's metadata with a comma, most PDF editors treat the comma as a delimiter and split the single name into several authors. This behavior comes from the editor, not from IronPDF, and it produces unexpected results when you mean to record one author.

To keep a name as a single entity, separate its parts with a vertical bar (|) or a hyphen (-) instead of a comma:

• Comma: Pdf.MetaData.Author = "Smith, John"; is often read as two authors.
• Vertical bar or hyphen: Pdf.MetaData.Author = "Smith | John"; stays one author.

The same issue has been discussed in the Adobe community:

• Metadata author field question
• Inserting authors into metadata without quotes

Choosing a non-comma separator keeps author names intact across the PDF viewers that apply this splitting.
