You can filter fonts by style, but only if they have been properly classified with Panose information. Professional fonts will contain this data, but not most free fonts. See this thread for explanation of the Panose system. Sort by the column heading PANOSE to see the result.
You can filter by many other ways, e.g. part of font name.
The numbers are Unicode numbers, you can also type characters using those numbers: e.g. Alter + 8364 = €
The ANSI Character set numbers corrolate exactly to the Unicode numbers in decimal. Alt 0255 = ÿ
Up to 126 you can dispense with the leading zero.
