url_decode: Decode URLs with ASCII punycode domains to Unicode

In punycoder: Unicode and Punycode Domain Name Processing

Decode URLs with ASCII punycode domains to Unicode

Description

Converts URLs containing ASCII punycode domain names back to their Unicode representation for display purposes. This function makes internationalized URLs human-readable.

Usage

url_decode(url, strict = getOption("punycoder.strict", TRUE))

Arguments

url	Character vector of URLs with ASCII punycode domains
strict	Logical; whether to apply strict validation. Defaults to 'getOption("punycoder.strict", TRUE)'.

Value

A character vector the same length as url, with each element containing the URL with its host portion decoded to Unicode. Only the domain component is transformed; scheme, path, query, and fragment are preserved. Elements corresponding to NA inputs are NA_character_.
