ReportLab doesn't do it.  Again, it would slow things to a crawl so
was never our focus, and in 15 years no customer has asked. On the
other hand, for document titles and one-page documents, it would not
be hard to have a 'draw kerned string' routine; PDF provides all the
primitives for it.

I honestly have no idea how many of the popular fonts these days have
kerning tables in them. Now that Google have made their fonts archive
available as a repo, it would be interesting to write an app to
explore them and run queries like that...
