Hi I am trying to analyze some PDF document which displays somewhere on one of the pages money sum and currency sign after it. Graphically it represents it correctly, however when I extract text from it I notice that currency sign is replaced with "{" symbol. When looking into format I notice that indeed currency symbol (164) is replaced with "braceleft" character name, which probably causes text extractor to be confused.

Why would PDF file encoder choose to replace character name with 'braceleft' instead of using 'currency'???

I have a database which contains a table with the following fields
id
data
timestamp
client_id
This was part of a very old web application that is no longer in use however is still been hosted in case we want to go back to to double check info. The field data currently is a string representing a file (xml, html and pdf). When the record is a pdf, I am trying to get the string
to open as pdf. I have done:
copy the string into notepad and save it as pdf. This open the file and matches the number of pages, but the pages looks blank.
I used a website like https://www.base64encode.org/ to encode the data as base64 and then I use a website like https://base64.guru/converter/decode/file to download the file, this does exactly the same as just saving the file as pdf where the downloaded file opens and display the same number of page but all of them are blank.
I am wonder what could i be missing to make this pdf to show their content?
In the ideal world I would like to run an script locally to generate this files and then uploaded them to S3 bucket, as we want to stop the server where this web application live

I was able to get access to sftp.
I run the below script and use filezilla to download the files.
Because the files where named after their ID's, we are able to link to the actual parent record
<?php
$db_con = mysqli_connect("localhost", "my_user", "my_pass","my_database");
if ($db_con->connect_error) {
die("Connection failed: " . $db_con->connect_error);
}
$sql = "SELECT id, data, app_id FROM my_table WHERE SUBSTRING(data, 1, 4) = '%PDF'";
$result = $db_con->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$fname = $row['id'].'-'.$row['app_id'].".pdf";
$myfile = fopen('pdf/'.$fname, "w") or die("Unable to open file!");
$txt = $row['data'];
fwrite($myfile, $txt);
fclose($myfile);
}
} else {
echo "0 results";
}
$db_con->close();
?>
I'm trying to create a visible PDF signature pragmatically. Non-visible signature works but when I add the AP (appearance) object I get an error in Acrobat Reader saying the following: 'Object label badly formatted'.
The relevant XObject that I make look like this:

I can't seem to find the error in this, but I must be missing something. I read this whole document by Adobe along with some other blogs and made my code according to that.
**UPDATE: **
I changed the code according to mkl's comment:

Here you can download my PDF.
UPDATE 2: It seems there was an error with my xref tables, where they weren't pointing to the right XObjects, that's why I was getting the error. However, now even though my PDF isn't corrupted and signature is ok (adobe will tell that the signature can't be verified because the certificate is self-signed but that's ok).
But now, I have another problem: The image doesn't appear. It's clickable and works but it's all blank.
A new version of the PDF is available here.
The issues you have come across are typical for projects implementing specific tasks of PDF editing without using a tested PDF library.
As discussed in comments, in the first file of which you only posted an excerpt there were fundamental syntax errors, in particular ignoring that for streams the specification requires The keyword stream shall be followed by an end-of-line marker.
Fixing that in your second file you yourself found broken cross reference entries.
Now you discuss the third file which appears to be properly signed as viewed in Adobe Reader, merely the image doesn't show up.
Actually, though, there still are multiple errors.
One reason for the image not showing up is that the image XObject stream is syntactically broken:
44 0 obj << /Length 9451 /Type /XObject /Subtype /Image /Filter /DCTDecode /BitsPerComponent 8 /Width 1300 /Height 1261 /ColorSpace /DeviceRGB
stream
...
Without looking into the values you set in the dictionary part of the stream, one already sees that the closing >> of that dictionary is missing. Thus, a PDF processor does not see where the image metadata ends and where the image payload starts.
In hindsight that was already visible in the previous files you posted, but there other issues first hit the eye.
Furthermore your cross references still are somewhat broken, many entries point to file offset 23 with some arbitrary generation number. At least some of the object numbers so treated are referenced in the document. This makes some programs already fail loading your PDF.
Also already discussed in comments, you tagged your question pades but use the SubFilter value adbe.pkcs7.detached. That is weird, if one starts implementing PAdES signing, why would one use the legacy profile?
I'm trying to write PDF files with c# and I also want to compress pdf streams. It is important not to use any 3rd parties libraries (DotNetZip etc..).
The only way for me to compress pdf streams is System.IO.DeflateStream but it seems that it doesn't work: when I compress a simple stream
BT
/F9 30 Tf
10 730 Td
(Hello World!) Tj
ET
PDF cannot decompress it and displays no text.
I have read similar topic
Is it possible to use the .NET DeflateStream for pdf creation?
but the answer contains broken link on MS bug report, and I'm not able to use any 3rd parties libraries in my project.
Is there any possibility to force DeflateStream work properly with pdf?
EDIT: source code
Here is how I write PDF object:
var resultLine = new StringBuilder();
resultLine.AppendFormatLine("{0} 0 obj", objectId);
resultLine.AppendFormatLine("<< /Length {0} /Filter /FlateDecode >>");
resultLine.AppendLine("stream");
WriteRaw(resultLine.ToString());
WriteRaw(DeflateCompress(content));
var footer = new StringBuilder();
footer.AppendLine();
footer.AppendLine("endstream");
footer.AppendLine("endobj");
It works perfect without deflate compression.
here is my Deflate method
public static byte[] DeflateCompress(string source)
{
using (var output = new MemoryStream())
{
using (var compress = new DeflateStream(output, CompressionMode.Compress))
{
var inBuffer = Encoding.UTF8.GetBytes(source);
compress.Write(inBuffer, 0, inBuffer.Length);
}
return output.ToArray();
}
}
input source variable is
"q\r\nBT\r\n/F9 30 Tf\r\n0 0 0 rg\r\n10 730 Td\r\n(Hello World!) Tj\r\nET\r\nQ\r\n"
out byte array is
{byte[61]}

when I do pdftk samplex.pdf dump_data_fields
I get back fields with format like:
FieldType: Text
FieldName: form1[0].Page1[0].Header[0].RepeatHeader[0].Project[0]
FieldNameAlt: Project
FieldFlags: 0
FieldJustification: Left
I have a sample that works with pdftk in filling in the fields, but it is a simpler format and the FieldNames are things like 'name'.
I try to merge the following fdf to get my infill for this field (as you can see below I try both the long name and the short name), but it doesn't seem to be working, any ideas on why?:

How are you generating your FDF? Here is an example FDF modified from a form I use pdftk with
field hierarchy like:
form1[0].Page1[0].Title[0]
form1[0].Page1[0].Item[0]
form1[0].Page1[0].Year[0]
form1[0].Page1[0].Desc[0]

<< /T (Item[0]) /V (Evo 3D) /ClrF 2 /ClrFf 1 >>
<< /T (Year[0]) /V (2011) /ClrF 2 /ClrFf 1 >>
<< /T (Desc[0]) /V (3D Smart Phone) /ClrF 2 /ClrFf 1 >>

] >>
]
>>
>> endobj trailer << /Root 1 0 R >> %%EOF
so you dont have the /Kids wrappers, and you arent using the field index numbers. Try modifying your FDF like my example to see if that works.
If you are a PHP user, you should check out pdftk-php. I use it on our server to inject mysql data into livecycle pdfs for a variety of uses and it takes care of the pdftk fdf injection part very nicely: http://www.andrewheiss.com/blog/2009/06/19/pdftk-php-officially-released/

I tried to fix this code with pdftk
pdftk 1.pdf output fixed.pdf
Error: Failed to open PDF file:

Errors encountered. No output created.
Done. Input errors, so no output created.
then I tried with cpdftk (from coherent), and gained further info
# cpdftk 1.pdf output fixed.pdf
cpdf could not read the file. Technical details follow:
Could not read x-ref table
finally I tried to fix file with Multivalent.jar

java -cp Multivalent.jar tool.pdf.Split -page 1 file.pdf
and Multivalent repaired pdf (I attach the result)
