What's the use-case for such a function?
void userFunction(CharsetEncoder charsetEncoder) { /* ... */ }
Not using Commons IO:
---CUT---
userFunction(csEnc == null ? Charset.defaultCharset().newEncoder() : csEnc);
---CUT---
vs using Commons IO:
---CUT---
userFunction(CharsetEncoders.toCharsetEncoder(csEnc));
---CUT---
IMO, the former call is clearer (self-documenting) and safer (explicit request
for a default).
