-/**
- * s32 Kanji_OffsetFromShiftJIS(s32 sjis);
- *
- * Returns the offset of the glyph texture data in the file `kanji` corresponding
- * to a given 2-byte Shift-JIS codepoint. No range validity check is carried out.
- *
- * 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 Original name: "LeoGetKadr"
