The Script, Decorative, and Handwriting typefaces often fail to provide numbers and special keyboard characters, such as the at sign, the ampersand (&), and the pound or hash tag (#) sign.Currently, there are three font formats compatible with personal computers, Macs, and other related devices: OpenType (OTF), PostScript (PS), and TrueType (TTF).These typefaces can fall into any one of the previous classifications, as long as they are “handwritten.”
