£ symbol it gets converted to £ when exported to MS Excel from JSP

We use the displaytag tag library to export data from JSP to MS Excel. When we encounter the pound symbol in the data £, it gets converted to £. Thus an amount of £5.00 looks like £5.00.

I tried to extend the ExcelView class of the displaytag tag library and overrode protected String escapeToColumnValue(Object value) and remove the rogue character but it again comes back when the data is exported into excel.

When I've seen problems like this historically it's been related to a mismatch in the character encoding of the source and destination, typically from a UTF-8 encoding to something else.

So in this case, you might want to try to convert the £ into a different encoding, perhaps ASCII encoding and see if that resolves the issue.

It would also depend I suppose on how you're currently encoding the symbol, whether it's a named entity, or if you're using a particular character code.
it's as dcowley explained: your jsp has to ensure that the data it reads from the backend is converted to a proper character set understood by the browser *and* that the web server anounces this character set properly (HTTP header *and* META tag in HTML)
then, if the browser sends back such data, you need to make the mapping reverse
