Describe the bug
A TOML document containing only invalid control characters should return an error.
For example, a file with on a single byte of 0x0b (vertical tab) or 0x0c (form feed) is an invalid TOML document.
Steps to reproduce (or a small repro code sample)
On Linux with zsh, create a file with only a vertical tab and consume with tt_decoder:
$ echo -n "\v" > tomlpp.1
$ hexdump -C <tomlpp.1
00000000 0b |.|
00000001
$ tt_decoder <tomlpp.1
{}
Additional information
The same file returns an error with other decoders, such as toml.dart:
$ decoder <tomlpp.1
Unhandled exception:
