 If a **lineWidth** is specified, input text values will be wrapped as needed to fit while preserving existing newlines. The line wrapping implementation is rudimentary: it replaces the space before the word that overflows with a line feed (`\n`). Lines might also be split on words that contain a soft-hyphen (`\xad`), replacing it with a hyphen (-). For non-ASCII, non-U.S. English text, or for when a different font is used, you may get better results by hard-wrapping the text yourself (by supplying line feeds in the input). If the **monospace** option is truthy, the default **fontFamily** changes to monospace and the **lineWidth** option is interpreted as characters (ch) rather than ems.
