Package `slug` generate slug from Unicode string, URL-friendly slugify with
multiple languages support.

## Example

```go
package main

import (
"fmt"
"github.com/gosimple/slug"
)

func main() {
text := slug.Make("Hellö Wörld хелло ворлд")
fmt.Println(text) // Will print: "hello-world-khello-vorld"

someText := slug.Make("影師")
fmt.Println(someText) // Will print: "ying-shi"

enText := slug.MakeLang("This & that", "en")
fmt.Println(enText) // Will print: "this-and-that"

deText := slug.MakeLang("Diese & Dass", "de")
fmt.Println(deText) // Will print: "diese-und-dass"

slug.Lowercase = false // Keep uppercase characters
deUppercaseText := slug.MakeLang("Diese & Dass", "de")
fmt.Println(deUppercaseText) // Will print: "Diese-und-Dass"

slug.CustomSub = map[string]string{
"water": "sand",
}
textSub := slug.Make("water is hot")
fmt.Println(textSub) // Will print: "sand-is-hot"
}
```

## Design

This library will always returns clean output from any Unicode string
containing only the following ASCII characters:

* numbers: `0-9`
* small letters: `a-z`
* big letters: `A-Z` (only if you set `Lowercase` to `false`)
* minus sign: `-`
* underscore: `_`

Minus sign and underscore characters will never appear at the beginning or
the end of the returned string.

Thanks to context-insensitive transliteration of Unicode characters to ASCII
output returned string is safe for URL slugs and filenames.

## Requests or bugs?

If your language is missing you could add it in `languages_substitution.go`
file.

In case of missing proper Unicode characters transliteration to ASCII you could
add them to underlying library:
