Summary: Erlang IDNA lib
Description:
A pure Erlang IDNA implementation that folllow the RFC5891.
- support IDNA 2008 and IDNA 2003.
- label validation:
* check NFC: Label must be in Normalization Form C
* check hyphen: The Unicode string MUST NOT contain "--" (two consecutive hyphens)
in the third and fourth character positions and MUST NOT start or end with a "-" (hyphen).
* Leading Combining Marks: The Unicode string MUST NOT begin with a combining mark
or combining character (see The Unicode Standard, Section 2.11 Unicode for an exact definition).
* Contextual Rules: The Unicode string MUST NOT contain any characters whose validity
is context-dependent, unless the validity is positively confirmed by a contextual rule.
To check this, each code point identified as CONTEXTJ or CONTEXTO in the Tables document RFC5892
MUST have a non-null rule. If such a code point is missing a rule, the label is invalid.
If the rule exists but the result of applying the rule is negative or inconclusive,
the proposed label is invalid.
* check BIDI: label contains any characters from scripts that are written
from right to left, it MUST meet the Bidi criteria rfc5893Maintainer: Aleksei Nikiforov
