### Public Instance methods

bbox()
encode_text(text, options={})

Perform any changes to the string that need to happen before it is rendered to the canvas. Returns an array of subset "chunks", where each chunk is an array of two elements. The first element is the font subset number, and the second is either a string or an array (for kerned text).

For Adobe fonts, there is only ever a single subset, so the first element of the array is "0", and the second is the string itself (or an array, if kerning is performed).

The `text` parameter must be in WinAnsi encoding (cp1252).

has_kerning_data?()
normalize_encoding(text)

built-in fonts only work with winansi encoding, so translate the string. Changes the encoding in-place, so the argument itself is replaced with a string in WinAnsi encoding.

width_of(string, options={})

calculates the width of the supplied string.

String must be encoded as WinAnsi
