getRangeAllFontNames
Get the fontNames from characters in range start (inclusive) to end (exclusive). For variable fonts, each entry includes variationSettings.
Supported on:
Signature
getRangeAllFontNames(start: number, end: number): FontName[]
Remarks
Throws if start === end (an empty range). Only call
node.getRangeAllFontNames(0, node.characters.length) when
node.characters.length > 0.
For empty text, load the node's concrete fontName with
figma.loadFontAsync before editing instead of
enumerating a range.
