Returns IDN restriction level of a string.
Project description
# 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:

## 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
#!/usr/bin/env python
import idncheck
idncheck.idencheck("φilosoφia", 3): # FIXME
print("I see what you're doing there")
