Returns the display width of a string. Assumes all characters with unknown widths are 0 width.

Given a number encoded in Locator16, convert it back to an integer.

Get the hash of a string. This util is currently used to generate an Int used for the internal pattern variable representation from the external pattern variable representation (String)
