Friendly name: Petite Capitals
Registered by: Tiro Typeworks / Emigre
Function: Some fonts contain an additional size of capital letters, shorter than the regular smallcaps and whimsically referred to as petite caps. Such forms are most likely to be found in designs with a small lowercase x-height, where they better harmonise with lowercase text than the taller smallcaps (for examples of petite caps, see the Emigre type families Mrs Eaves and Filosofia). This feature turns lowercase characters into petite capitals. Forms related to petite capitals, such as specially designed figures, may be included.
