it should still fix some issue I don't know much about PDF encoding, but I think you can solve your particular problem by modifying pdf.py. In the PageObject.extractText method, you see what's going on:
code :
def extractText(self):
    [...]
    for operands,operator in content.operations:
        if operator == "Tj":
            _text = operands[0]
            if isinstance(_text, TextStringObject):
                text += _text
        elif operator == "T*":
            text += "\n"
        elif operator == "'":
            text += "\n"
            _text = operands[0]
            if isinstance(_text, TextStringObject):
                text += operands[0]
        elif operator == '"':
            _text = operands[2]
            if isinstance(_text, TextStringObject):
                text += "\n"
                text += _text
        elif operator == "TJ":
            for i in operands[0]:
                if isinstance(i, TextStringObject):
                    text += i
def extractText(self, Tj_sep="", TJ_sep=""):
        if operator == "Tj":
            _text = operands[0]
            if isinstance(_text, TextStringObject):
                text += Tj_sep
                text += _text
        elif operator == "TJ":
            for i in operands[0]:
                if isinstance(i, TextStringObject):
                    text += TJ_sep
                    text += i
In [1]: pdf.getPage(1).extractText()[1120:1250]

This might help you I am generating a PDF file using the pyPdf library in python. , Using reportlab library will solve the problem:
code :
from reportlab.pdfgen import canvas

c = canvas.Canvas("hello.pdf") 
c.drawString(100,750,"Welcome to Reportlab!")
c.save()
