+ * The terminal layer is an abstraction on top of the TTY layer and the
+ * console interface.  It can be used by system console drivers to
+ * easily interact with the kernel console and TTYs.
+ *
+ * Terminals contain terminal emulators, which means console drivers
+ * don't need to implement their own terminal emulator. The terminal
+ * emulator deals with UTF-8 exclusively. This means that term_char_t,
+ * the data type used to store input/output characters will always
+ * contain Unicode codepoints.
+ *
+ * To save memory usage, the top bits of term_char_t will contain other
+ * attributes, like colors. Right now term_char_t is composed as
+ * follows:
+ *
+ *  Bits  Meaning
+ *  0-20: Character value
+ * 21-25: Bold, underline, blink, reverse, right part of CJK fullwidth character
+ * 26-28: Foreground color
+ * 29-31: Background color
