Getting special character in getting contents of formula based cell using JXL API in Java

Question

I am facing a problem while getting contents of cell using the JXL API, if I am using a formula in an Excel sheet.

Right now I am using the formula IF($L10="","",+ROUND($L10*1.375,3)) in each cell, but when the cell value is blank I am getting junk characters when I call the cell.getContents() method. The code snip is as follows.

Workbook = Workbook.getWorkbook(p_sourceFile);
excelsheet = workbook.getSheet(0);
...

for (int row = 1; row < noOfRows; row++)
{
    cell = excelsheet.getCell(col, row);
    content = cell.getContents();
    System.out.println("content-" + content); -- Is giving me junk character? when the cell value is blank.
