Solution

Opening the file we can quickly tell that the entire file has been written in two fonts. We unzip the docx file, and grep the part we are interested in.

$ unzip Macbeth.docx

$ grep "Bitstream Vera Sans Mono\"/></w:rPr><w:t>\(.\)<" document.xml -o
Bitstream Vera Sans Mono"/></w:rPr><w:t>F<
Bitstream Vera Sans Mono"/></w:rPr><w:t>l<
Bitstream Vera Sans Mono"/></w:rPr><w:t>a<
Bitstream Vera Sans Mono"/></w:rPr><w:t>g<
Bitstream Vera Sans Mono"/></w:rPr><w:t>:<
Bitstream Vera Sans Mono"/></w:rPr><w:t>F<
Bitstream Vera Sans Mono"/></w:rPr><w:t>u<
Bitstream Vera Sans Mono"/></w:rPr><w:t>c<

Bitstream Vera Sans Mono"/></w:rPr><w:t>e<
Bitstream Vera Sans Mono"/></w:rPr><w:t>n<
Bitstream Vera Sans Mono"/></w:rPr><w:t>s<
Bitstream Vera Sans Mono"/></w:rPr><w:t>i<
Bitstream Vera Sans Mono"/></w:rPr><w:t>c<
Bitstream Vera Sans Mono"/></w:rPr><w:t>s<
