StringWidthUTF8 (function)

Returns the length, in inches, of the string as it would be displayed on a page, using the current font. Bear in mind that the com-

bination of many bytes sometimes results in a single glyph and that text orientation can also affect the number of glyphs dis-

played.

mode

String specifying how the contextual analysis is to be performed. Possible values are 'normal', 'reverse', and 'none' (for no con-

textual analysis).
