Review ttx conversion report

There is report of ttx conversion script. This script was executed from root folder in Google Font Directory repo clone:

``` sh
find . -name "*.ttf" -exec ttx -s -o {}.ttx {} \;
find . -name "*.otf" -exec ttx -s -o {}.ttx {} \;
```

I think it need to be reviewed because sometimes script wasn't successful
