How does bea or tomcat encode filenames with special chars?

[mlv2312]

Hi,

I am experiencing problems with my href links containing filenames
with portuguese chars. For example, 'FUNDAMENTOS P REGULAMENTAÇÃO DA
CIDE.tif'.

However, if I open the listing files JSP on tomcat and click on the
right link, the same file opens. Then, I opened the source html code
generated for the listing files JSP, and I realized that the filename
was encoded as following:

'FUNDAMENTOS%20P%20REGULAMENTA%C3%87%C3%83O%20DA%20CIDE.tif'

I tried to encode the filename using the javascript function
'escape()', but the result was different:

'FUNDAMENTOS%20P%20REGULAMENTA%C7%C3O%20DA%20CIDE.tif'

I tried URLEncoder.encode, but the result was not the same...

Does anyone know which algorithm bea/tomcat use to encode special
chars?

Where can I find the appropriate information?

Best regards!

Marcelo

This uses the UTF-8 encoded diacritics.

I tried to encode the filename using the javascript function
'escape()', but the result was different:

'FUNDAMENTOS%20P%20REGULAMENTA%C7%C3O%20DA%20CIDE.tif'

While this uses ISO-8859-1[5].

I tried URLEncoder.encode, but the result was not the same...

It would, but don't use the deprecated encode( String s ). If you
specify "UTF-8" as encoding, it will give you the first form, and if
you specify "ISO-8859-1", the second.

Does anyone know which algorithm bea/tomcat use to encode special
chars?

The same as your JS code, just with a different encoding.

Where can I find the appropriate information?
