I want to write some text into a pdf. I have the data in "icrResultTxt". I am also writing the data to
text.txt
file before trying to write to a pdf. When I try to write to the pdf I get "
No glyph for U+000A in font Helvetica-Bold
". How to solve it? I dont have any fondness for "Helvetica-Bold". I am willing to change to any font.
