Hi
this is another file have similar problem , the file format is RTF

also convert to PDF

the result of PDF :

847×149 9.54 KB

segemented from the RTF:

{\fldrslt {\rtlch\fcs1 \af0 \ltrch\fcs0 \lang1024\langfe1024\kerning2\noproof\insrsid3932176 \loch\af0\dbch\af18\hich\f0 \hich\af0\dbch\af18\loch\f0 MR.

}

\u26446 is the unicode (in HTML representation) of 李
\u26481 is the unicode (in HTML representation) of 東

You can find that there is a ‘?’ literal following the two unicode characters. It seems, in RTF standard, it is a presentation of fallback character. Say, for literal \u26446\?, it means if the rendering program cannot find a font presentation of \u26446, it should display a ‘?’

Does anyone know how to resolve it?

@Ykworm Could you please zip and attach the whole problematic RTF document so we can test with it?

#1 for these 2 reason , I can’t upload the test file:

  1. casue of confidentiality agreement .
  2. after modified the file by MSWord , the problem is fixed automitically(“?” is disapear and the text that was not displayed can be displayed using the new file conversion). it means I can’t delete the content that need for confidentiality.

#2 I tired convert the rft to PDF , the “𧙗” is disapeal ,

source rtf :

gened file:

but if I do
step 1: rtf → png
step 2: png → PDF

succeeded !!!

Does anyone know why ?

@Ykworm Unfortunately, it is impossible to tell what might cause the problem on your side without ability to reproduce the problem on our side. And we cannot reproduce the problem without the problematic documents.

IC ，btw ：
May I ask , Can the Aspose DOC-PDF library handle the 4-byte character ?

9

@Ykworm Do you mean surrogate pair characters? Yes, Aspose.Words supports them. If possible, please attach a sample document with problematic characters here for testing. This will hep us to analyze and if require resolve the problem.

I finally edited a file that can display the problem ：
b-new.zip (4.4 KB)

We can see if the word “𧙗” can be displayed when opening a file using MSWord (It seems that only Word can display correctly)

854×553 4.68 KB

after convert to PDF, “𧙗” has been lose.
