The other problem is that reading characters from sockets directly into
a std::string (which uses the platform character set and encoding) is
inherently unportable. Even if the incoming encoding is ASCII, the
platform might still use EBCDIC. Far more likely is that incoming is
UTF-8 and local ISO-8859-1 or Windows-1252 (typical Linux and Win32
platforms), which would still cause problems on German umlauts and
similar characters.
read_string would therefore have to supply a recoding function to safely
import characters.
