As an example, if I create a PDF using following code:
```py
def test_fn():
# I want this indentation preserved
print("123")
```
I get the following output:
This looks nice and all, but if I try to copy this code out of the PDF, the indentation is lost:
def test_fn():
# I want this indentation preserved
print("123")
which is rather unfortunate for python code.
Is there any way to preserve the indentation characters?
