\a charArray has a glyph for the font.
\brief Fills out \a hasArray with whether or not the font has a glyph
for each character in \a charArray.
\c true is written in \a hasArray if the character has a glyph in the
current font and \c false is written in \a hasArray if the character
does NOT have a glyph in the current font.
\c true is written in \a hasArray if a glyph is found for the character,
\c false otherwise.
\remark After the introduction of fallback fonts for missing glyphs,
this is not exaclty what the name or the original desciption imply. As
the objective of this method is to know if a string can be presented
to the user without getting "no glyph" symbols, it will still write
\c true if the queried font does not provide a glyph for a character
but a fallback font does.
\param charArray The source character array.
\param numChars The number of characters to consider in \a charArray.

\c true is written in \a hasArray if the character has a glyph in the

in the search if \a useFallbacks is \c true.
