Currency Signs being displayed as empty white boxes

[byron.ullauri]

I have a variable that checks the value of a column (currency name) and returns its currency sign through a series of ifs/else. 

When viewed in jaspersoftstudio, it shows an empty box in preview and when exporting.
On the server, the preview shows the currency sign but when exporting to pdf, the empty box returns.

I've tried:

• Copying and pasting the symbol itself
• Using the Unicode value and returning it as a string
• Using html codes like £ and setting the format option on textfield to html

Any idea on how to fix this?

The font you're using probably is missing the currently sign. Try setting up font extensions.

I did add the font using font extensions, though it is worth noting that the file ext for the font is .otf instead of .ttf

I think JasperReports only supports .ttf. I've also tried some other extensions and wasn't successful.

Yes, this seems to be the case. Couldn't find a .ttf version of the font I'm using so I tried looking up if there was a way to convert .otf to .tff, managed to do it but still no dice on getting currency symbols to show up.  My solution was to change the font being used for fields that had the currency signs.
