Currency symbol (eg £ or $) causing error

```
What steps will reproduce the problem?
1. Do a Currency format on number (eg. 10.65 to either £10.65 or $10.65)
2. $data = new Spreadsheet_Excel_Reader("$filename",false);
3. print_r($data);

What is the expected output?

Array output from;
$data = new Spreadsheet_Excel_Reader("$filename",false);
$rows = $data->rowcount($sheet_index=0);
$cols = $data->colcount($sheet_index=0);
print_r($data);
...
[6] => $55.43
[7] => $44.95
...

What do you see instead?

Array output from;
$data = new Spreadsheet_Excel_Reader("$filename",false);
$rows = $data->rowcount($sheet_index=0);
$cols = $data->colcount($sheet_index=0);
print_r($data);
...
[6] => [$$-55]55
[7] => [$$-45]45
...

Please provide any additional information below.

[7] => [$£-67]67

Start by reproducing the reported case with Spreadsheet_Excel_Reader using an Excel file containing £10.65 or $10.65 currency-formatted cells, then inspect how the reader handles the resulting currency format strings. Confirm that the parsed array contains the displayed currency values rather than strings such as [$$-55]55 or [$£-67]67.
