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 combination of many bytes sometimes results in a single glyph and that text orientation
can also affect the number of glyphs displayed.

stringwidthutf8(text, mode)
Arguments
text — UTF8 text string to be measured.
mode — String specifying how the contextual analysis is to be performed. Possible values are 'normal',
'reverse', and 'none' (for no contextual analysis).
Strip (function)
Removes all occurrences of a string within another string.
Syntax
strip( string1, string2 ) string value
Arguments
string1 — String value to be removed from string2.
string2 — String value to change.
