Ever wondered how to make a code formatter? This post does a good job showing the main problems you might encounter. The impact of Unicode is especially funny. Very interesting stuff.

OK more questions than answers I guess... That said, it shows interesting differences in design choices with C++ to support the traits system.

So much data trapped in PDFs indeed... Unfortunately VLM are still not reliable enough to be unleashed without tight validation of the output.

Nice post. Explains well why the answer is not a number to target. You want to impact the distribution.
