# IDNCheck

IDNcheck performs safety checks on international domain names.

This might be useful if you want to see how likely a given domain

is to be used for nefarious purposes such as phishing.

It returns the unicode restriction level passed by a string, as described

in Unicode Technical Standard #39, Unicode Security Mechanisms (see References).

Note: On first run, it will automatically download a file if it doesn't exist:

http://www.unicode.org/Public/UNIDATA/Scripts.txt

## How to use

Typical usage might look something like this:

```python

>>> import idncheck

>>> idncheck.idncheck("hello")

1

>>> idncheck.idncheck("φilosoφia")

42

>>> idncheck.idncheck("φilosoφia", 3) # FIXME

True

>>> idncheck.idncheck("paypal")

1

>>> idncheck.idncheck("paypаl")

4

>>> idncheck.idncheck("раура1")

4

```

or

```python

#!/usr/bin/env python

import idncheck

idncheck.idencheck("φilosoφia", 3): # FIXME

    print("I see what you're doing there")

```
