No, but remembering how to do this is a pain:
File out = ...
Charset charset = ...
CSVPrinter printer = new CSVPrinter(new OutputStreamWriter(new
FileOutputStream(out), charset), format);
Instead of:
format.print(file, charset);
We can roll these two APIs back out and document that the components only
provides low-level APIs, forget convenience APIs.
We can also find a better home for these APIs... like where? On the printer
static side?
