UTF-8 encoding for HTML

2003-06-09 11:46

Hi Teodor,

 

I've been using JasperReports to generate reports in PDF, HTML, and CSV. I need to be able to display international characters - basically every character in the Unicode spec. I noticed that when I generated HTML reports, some characters were displayed correctly, but some weren't.

 

I took a look at the JRStringUtil.xmlEncode() method that you use to encode special characters. I found that the characters you encode using this method were the ones that were NOT appearing correctly on the exported HTML report. I needed to change my browser's encoding to Western European in order for them to show up correctly; because the exported report was declared to be UTF-8 encoded, this was what the browser was set to by default.

 

I then changed the xmlEncode() method to simply encode the string to UTF-8, and this worked nicely - the characters in the exported report appeared correctly.

 

Since the exported reports are declared to be UTF-8 encoded, why did you use HTML entities rather than UTF-8 encoding? Can I add my change to the JasperReports code?

 

thanks,

 

Chris

Anybody running into this problem too? I have set the encoding to ISO-8859-1 (though it could be UTF-8) and it is not converting to the correct characters:

I am not sure if it is related to the suggestion above. Any help would be greatly appreciated =)

 

Thanks!

Kris

OK I found the solution on another thread (Thanks Teodor!)

 

Apparently I need to check the box that says "Is Styled Text" and then it won't convert my & to & and display the unicode chars correctly.

 

Here's the link to the original thread:

Sorry if I messed up this thread! (Doesn't seem like my problem had anything to do w/ the xmlParser util).

Hello,

 

   I'm working with jasper 0.6.7, before print, i can see (HTML) the right display, but when I try to see the PDF, the chars were written unescaped:

   HTML:

   PDF: Ó Ô Õ Ö Ø Ù Ú Û Ü Ý Þ

   Some chars are converted ok as well, like Ú, for example. I attached the screen format of the text field.

I would see the same chars in HTML and PDF as well.

 

Thanks and regards,
Zulu.
