Perhaps just the ASCII isprint characters?\r\n\r\nhttp://www.cplusplus.com/reference/cctype/isprint/\r\nFor the standard ASCII character set (used by the \"C\" locale), printing characters are all with an ASCII code greater than 0x1f (US), except 0x7f (DEL).\r\n\r\nJust for comparison, string literals in Go: https://golang.org/ref/spec#String_literals. Not too complex, but I'm not certain we need that functionality."}}
