You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ot_shape_normalize.go
    path of file: ./repos/caire/vendor/github.com/go-text/typesetting/harfbuzz
    
    the code of the file until where you have to start completion: package harfbuzz

/*
 * HIGHLEVEL DESIGN:
 *
 * This file exports one main function: otShapeNormalize().
 *
 * This function closely reflects the Unicode Normalization Algorithm,
 * yet it's different.
 *
 * Each shaper specifies w
