Bug Description

In the attached hello_world.pdf file, the text is being drawn by the following TJ command (operand, operator):

[['\x01', -13.8818, '\x02', 17.0689, '\x03', -5.16561, '\x03', -5.16561, '\x04', 2.15722, '\x05', 3.67949, '\x06', 2.5903, '\x07', -0.30418, '\x04', 2.15654, '\x08', 2.23293, '\x03', -5.16561, '\t', 11.3788, '\n', 6.60875, '\x06']] 'TJ'

The bytes being drawn are using the font \R7 (['/R7', 10.7452] 'Tf').

The font \R7:

7 0 obj
<</BaseFont/RDZRPI+Calibri/FontDescriptor 8 0 R/ToUnicode 11 0 R/Type/Font
/FirstChar 1/LastChar 10/Widths[ 623 498 229 527 250 226 715 349 525 252]
/Encoding 12 0 R/Subtype/TrueType>>
endobj

Encoding:

12 0 obj
<</Type/Encoding/BaseEncoding/WinAnsiEncoding/Differences[
1/g44/g286/g367/g381/g853/g3/g449/g396/g282/g856]>>
endobj

PyPdf does not support reading a custom encoding from the document while drawing text, and therefore the extractText method does not return any text for this file.
