Dear PodofoTeams??
Thanks for replying to my question.
Yes, I used the utf8 encoding method, but I still cannot input the correct
Chinese characters into the PDF. During the debugging process, I found that the
printed fontname is suruma. I don??t know if this is caused by the failure of
my related font library installation.
This code is from Createtiontest.cpp??
pFont = pDocument->CreateFont( "Arial Unicode MS", new
PdfIdentityEncoding( 0, 0xffff, true ) );
printf("GOT: %s\n", pFont->GetFontMetrics()->GetFontname()
);
PdfString sJap(reinterpret_cast<const
pdf_utf8*>("??Po\tDoFo???????????????Z????????????"));
const long lUtf8BufferLen = 256;
pdf_utf8 pUtf8Buffer[lUtf8BufferLen];
pdf_utf8 const str[] =
{0xe3,0x80,0x8c,0x50,0x6f,0x5c,0x74,0x44,0x6f,0x46,0x6f,0xe3,0x80,0x8d,0xe4,0xb8,0xad,0xe6,0x96,0x87,0xe6,0xb5,0x8b,0xe8,0xaf,0x95,0x00};//po\tdofo????????
PdfString sCHN(str);
PdfString::ConvertUTF16toUTF8( sJap.GetUnicode(),
sJap.GetUnicodeLength(), pUtf8Buffer, lUtf8BufferLen );
printf("UNIC: %s\n", pUtf8Buffer );
pFont->SetFontSize( 18.0 );
pPainter->SetFont( pFont );
pPainter->DrawText( 100.0, 100.0, sJap );
pPainter->DrawText( 200.0, 200.0, sCHN );
The message typed in the terminal by this code??

This is a screenshot of the PDF
Env: linux (ubuntu18.04)
Lib: freetype2.10.0, fontconfig2.13.91, podofo0.9.7
Although I cannot use the drawtext() function or the DrawMultiLineText()
function to write Chinese, I found that the annotation_freetext can be used to
write Chinese Correctly, but it cannot be previewed or sent to the printer for
printing. The same after using SetFlags(0x0004).The code is the
CreateUnicodeAnnotationFreeText() function in test/Creationtest/Creationtest.cpp
thank you very much

You are telling the compiler to simply interpret the memory of the string as
UTF-8. Are you sure that is the encoding your compiler is using?
Could you try using something like this, just to make sure the encoding gets
through correctly?
pdf_utf8 const str[] = {0xe3,0x80,0x8c,0x50,0x6f,0x5c,0x74,0x44,0x6f,0x46,0x6f,
0xe3,0x80,0x8d,0xe4,0xb8,0xad,0xe6,0x96,0x87,0xe6,0xb5,0x8b,0xe8,0xaf,0x95,0x00};
PdfString sJap(str);

Subject: [Podofo-users] drawtext()function can not add CJK text to PDF
Deatr podofoteams:
I recently used podofo to add text to the PDF, but found that the correct
Chinese cannot be added to the PDF under linux (ubuntu). The code I used is the
following paragraph:
pFont = pDocument->CreateFont( "Arial Unicode MS", new
PdfIdentityEncoding( 0, 0xffff, true ) );
printf("GOT: %s\n", pFont->GetFontMetrics()->GetFontname()
);
PdfString sJap(reinterpret_cast<const
pdf_utf8*>("??Po\tDoFo??????????"));
const long lUtf8BufferLen = 256;
pdf_utf8 pUtf8Buffer[lUtf8BufferLen];
PdfString::ConvertUTF16toUTF8( sJap.GetUnicode(),
sJap.GetUnicodeLength(), pUtf8Buffer, lUtf8BufferLen );
printf("UNIC: %s\n", pUtf8Buffer );
pFont->SetFontSize( 18.0 );
pPainter->SetFont( pFont );
pPainter->DrawText( 100.0, 100.0, sJap );
In addition to this, I also used
const PdfEncoding* pp = PdfEncodingFactory::GlobalIdentityEncodingInstance();
PdfFont* pFont = document.CreateFont("SimHei", true, true, false,
pp);//Helvetica
painter.SetFont( pFont );
double w = pPage->GetPageSize().GetWidth();
double h = pPage->GetPageSize().GetHeight();
PdfString str((pdf_utf8* )"????podofo???????????????????????????? \n \n");
painter.DrawMultiLineText( 0, 0, w, h, str);
After I use this code, I cannot find these words in the PDF, so I seek your
help and hope to get a reply, thank you
best wishes
