* A nice Shift-JIS codepoint table: https://uic.io/en/charset/show/shift_jis/
* The file `kanji` contains the 'Level 1' kanji (0x889F-0x9872), and a reworked
* version of the non-kanji section that includes extra English and Hylian glyphs.
*
* @note This function assumes that its argument is a valid Shift-JIS codepoint;
* there is no range protection at all.
*
* @param sjis Shift-JIS Codepoint of glyph.
* @return s32 offset into `kanji` file.
*
* @remark Almost identical to "LeoGetKadr" from libleo.
