Hi,
You did not send enough details. I can only guess what font name you
used and how you draw string but when I tested your text it shows in
pdf without spaces. Btw base14 fonts cannot be used with identity
encoding.

Hello.
I try to create PDF file with PoDoFo library. I want to draw
multi-language text in my PDF file.
For this I create PdfFont with:
PdfFont * createFont( const QString & name, bool bold, bool italic,
float size,
PdfStreamedDocument * doc )
{
auto * font = doc->CreateFont( name.toLocal8Bit().data(), bold,
italic , false,
PdfEncodingFactory::GlobalIdentityEncodingInstance() );
if( !font )
PODOFO_RAISE_ERROR( ePdfError_InvalidHandle )
font->SetFontSize( size );
return font;
}
It works. I see English and Russian text in output PDF, but...
Assume I have text: "The book Книга"
It writes to PDF but in the output all characters are separated with
space, like:
"T h e b o o k К н и г а"
How can I solve this issue?
Thank you.
