While using PD4ML for pdf creation, I have noticed that there is a problem with HTMLs that contain Chinese characters.
Those characters are Chinese and can be seen in their normal form in the source html.

I am not able to copy hindi content from pdf file. When I am trying to copy/paste that content it changes to different hindi characters.
Example-
Original- विधान सभा
After paste- नरधरन सभर
it shows like this.
Can anybody help me to get the exact hindi characters.
What was used to create the PDF?
It was likely been created with an embedded font subset and no toUnicode mapping. Basically the codes of the characters used in the content of the PDF are mapped to glyphs embedded in the PDF which are displayed, but there is no mapping from these codes to regular Unicode codes so copying them produces gibberish. The only way to extract the original contents would be with some form of OCR.
Another possibility is that the application you are pasting it into is not shaping the characters correctly.
I am using iTextSharp to fill pre-defined fields on an existing PDF document. all the apostrophes are replaced by an at sign in Hebrew words, I tried to embed the font to the document using Preflight but the embedding failed. How do I get the output PDF to display the text including the apostrophes?
Thanks
I am extracting text from a PDF file using PdfBox. When the PDF does not contain any embedded fonts everything works fine. The problem occurs when there are some TrueType embedded fonts. I discovered that in same cases the embedded fonts replace the shape of default characters with some other shapes. For example a char code for 'ï' is used to encode 'ł'. I am aware that I cannot get the real shape of the character without any mapping or OCR. I would like to know which characters might be redefined by the embedded characters. My question is how can I know which characters in the PDF stream are defined by the embedded fonts?
I am using FPDF to create a PDF and tFPDF to allow for unicode characters, such as Chinese, Japanese, or Korean.
I am using the ex.php that was in the tFPDF example files.
I added some Japanese and Chinese Characters to the Hello World.txt file, but those characters are not showing up, even in the default DejaVu font that was included.
What do I need to do to make other characters like Japanese, Chinese, Korean show up?
The API that you're using needs to provide specific support for encoding the unicode characters that you're trying to add to the document. This is done by way of a codepage / charset for those characters. There are a number of different charsets available for Japanese, Chinese and Korean characters such as Hangeul, GB2312, Chinese Big 5, Shift JIS, etc.
The API that you're using needs to support the charset that matches the text which you're trying to add.
It looks like FPDF supports some Chinese codepages since there's some info on their forum about adding text using GB2312 and Chinese Big 5, but as they don't appear to mention unicode on their main pages, my guess is that they don't provide extensive support for it.
There is a multi byte version of fpdf called mbfpdf (freely available I suppose). With that and the PGOTHIC font, it is possible to display Asian characters. I have used this class (mbfpdf) to create a few pdf files myself and it worked well.
I want to export a .pdf file. That step is ok. But the problem I have is that this PDF does not show our native language. An example, English words are fine, but Chinese words are not shown in the report. How can we show the Chinese words too? We are programming in VB.NET.
I have had good luck using the itextsharp library to create pdf files from my VB.NET apps. The important thing to remember for proper display of alternate characters sets (Russian, Chinese, Japanese, etc.) is to use IDENTITY_H encoding when creating the BaseFont.
Dim bfR As iTextSharp.text.pdf.BaseFont
bfR = iTextSharp.text.pdf.BaseFont.CreateFont("MyFavoriteFont.ttf", iTextSharp.text.pdf.BaseFont.IDENTITY_H, iTextSharp.text.pdf.BaseFont.EMBEDDED)
You want to set the PDF to use unicode to display chinese characters. Depends how you export the PDF file. If you use XSL-FO you convert the characters to their unicode equivalent in teh following format:
&#<UnicodeNumber>
