I have a 14MB TTF containing mostly Simplified Chinese characters.

I'd like to reduce the size by creating a subset which only contains the specific characters within an HTML page.

So, ideally, I'd like to pass a (Linux) program an block of text and have it recreate the font based on the characters contained.

E.g.

```
 ./magic-font-squisher input.tff "ABC123水小长"

```

or

```
 ./magic-font-squisher input.tff /path/to/test.html

```

The new font would then only have those 9 characters present.
