deleted letters from PDF even if those letters were present in the source document

[jakubsiast]

I used pdf-redactor to change some text in a pdf file, but in part of the pdf I've lost all the 'n' characters.
The affected text was not the one that I hoped to change. The text was handled in the "class TextToken" by the "str(self)" function as an unchanged text, i.e., it passes through condition "if self.value == self.original_value:". Nevertheless it has changed. What I managed to do is to track that the function to blame is "PdfString.from_bytes(...)" in line 379 of pdf_redactor.py:
# If unchanged, return the raw original value without decoding/encoding.
return PdfString.from_bytes(self.raw_original_value)
By forcing the encoding of the unchanged TextToken to 'hex' I managed to fix the issue:
return PdfString.from_bytes(self.raw_original_value, bytes_encoding = 'hex')
This simple change helped in my case, but I do not know if it is a general case. Can you try this and, eventually push this fix to your code?
