TryDumpSpecialEscapedChar()

static bool TryDumpSpecialEscapedChar ( Stream &  s, const char  c  )

static

Prints the specific escape sequence of the given character to the stream.

If the character doesn't have a known specific escape sequence (e.g., '', '
' but not generic escape sequences such as'\x12'), this function will not modify the stream and return false.
