Title: Fix some warnings and a test

* fix `warning: implicit conversion loses integer precision: 'long' to 'int'`
* extconf already sets `-Wextra`, no need for `-Wall`. Also add `-Wno-comment`. There will be wildcard refs or filepaths in the docs. The warning is just noise.
* on my machine:
```ruby
"A\314\212ngstro\314\210m" == "Ångström" #=> false
```
