By the time FOP gets this information, the XML has been parsed. □ is just a convenient way of entering the single character with Unicode value 25A1, □, WHITE SQUARE. Equivalents would be □ or (with common ISO entity declarations) □ — in all cases, FOP just receives a single character, □. FOP then attempts to find which of the specified fonts actually has a glyph for that character, and does so using the numeric Unicode value of the character, but that is independent of how the input XML (which FOP does not see) specified the character. If you’re looking at altering or overriding the code, you need to operate in the character domain, not the XML markup domain. (By analogy, FOP receives elements, root-in-the-FO-namespace etc., not the string “<fo:root ...”. This is the same kind of thing.) ~Chris -- Chris Maden, text nerd <URL: http://crism.maden.org/ > “The present tendency and drift towards the Police State gives all free Americans pause.” — Alabama Supreme Court, 1955 (Pike v.
