* Unless you are using a very special font, the default character is '0' (zero),

*
* Please note, that the width set by this method includes 4 pixels of margin padding (two on each side),
* plus 1 pixel padding for the gridlines (Section 3.3.1.12 of the OOXML spec).
* This results is a slightly less value of visible characters than passed to this method (approx. 1/2 of a character).
*
* To compute the actual number of visible characters,
* Excel uses the following formula (Section 3.3.1.12 of the OOXML spec):
*
* {@code
* width = Truncate([{Number of Visible Characters} *
* {Maximum Digit Width} + {5 pixel padding}]/{Maximum Digit Width}*256)/256

* If you set a column width to be eight characters wide, e.g. {@code setColumnWidth(columnIndex, 8*256)},
* then the actual value of visible characters (the value shown in Excel) is derived from the following equation:
* {@code
* Truncate([numChars*7+5]/7*256)/256 = 8;
* }
