RE: Surrogate pair error

HI,

 

Can you set the font-family in the fo file and add a font to the fop.xconf?

 

Thanks

Subject: Surrogate pair error

 

Hi everybody,

 

 

We have a document containing the following character: Unicode Character
'CYPRIOT SYLLABLE RO' (U+10826)

When running fop (2.4) to render a pdf, it fails with the exception pasted
below. Attached you can find a sample fo file that contains the character
and produces the error.

I understand that fop 2.3 introduced support for surrogate pairs.

Is this a bug, or are we missing something?
