- The font for the numbers is specified as
"sans-serif", rather than being a specific monospace font such as Courier. The extension should either check the system for a few fonts and use a suitable one, or use fixed paths. 2. The numbers are laid out using spaces instead of the "dx" attribute (kerning), so the spacing is more font-dependent than it should. 3. The layout of numbers looks nothing like the example in Wikipedia, and the quiet zone mark ">" on the right is missing.
Thanks for the bug report. You've prompted me to push my code cleanup from last year and test everything.
I'm not sure about dx units, I know the text attribute is made in Barcode/Base.py:109 and is as basic as it gets. It doesn't even set a font, I think inkscape must do that.

For ISBN numbers OCRB font is the commonest usage although OCRA is still seen on some important books like Masterson's "Book design and Production".
