+ * 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
