When exporting a specific document with a CIDFontType0 font (Korean TAWBUL+HGGGothicssiP80g or BPRSCV+HGGGothicssiP60g) the document is wrongly exported which leads to missing content.
Workaround:
After import you can change the font:
pdfDocument = provider.Import(memory);
FontBase malgunGothicFont;
FontsRepository.TryCreateFont(new FontFamily("Malgun Gothic"), out malgunGothicFont);
foreach (RadFixedPage page in pdfDocument.Pages)
{
foreach (ContentElementBase element in page.Content)
{
TextFragment textFragment = element as TextFragment;
if (textFragment != null && (textFragment.Font.Name == "TAWBUL+HGGGothicssiP80g" || textFragment.Font.Name == "BPRSCV+HGGGothicssiP60g"))
{
textFragment.Font = malgunGothicFont;
}
}
}
