toUnicode(domainName[, options])

Converts a case-folded Punycode string of ASCII symbols to a string of Unicode symbols.

Available options:

• checkBidi
• checkHyphens
• checkJoiners
• ignoreInvalidPunycode
• transitionalProcessing
• useSTD3ASCIIRules

Options

checkBidi

Type: boolean Default value: false When set to true, any bi-directional text within the input will be checked for validation.

checkHyphens

Type: boolean Default value: false When set to true, the positions of any hyphen characters within the input will be checked for validation.

checkJoiners

Type: boolean Default value: false When set to true, any word joiner characters within the input will be checked for validation.

ignoreInvalidPunycode

Type: boolean Default value: false When set to true, invalid Punycode strings within the input will be allowed.

transitionalProcessing

Type: boolean Default value: false When set to true, uses transitional (compatibility) processing of the deviation characters.

Similar packages

Other packages similar to tr46

punycode

Punycode.js is a robust Punycode converter that fully complies with RFC 3492 and RFC 5891, and works on nearly all JavaScript platforms. This package is used to convert Unicode strings to Punycode and vice versa, similar to tr46's toASCII and toUnicode functions. However, tr46 provides additional processing options and is designed to comply with the TR46 algorithm.

idna-uts46

The idna-uts46 package is a small library that converts a Unicode string to an ASCII string as per the IDNA2008 (UTS #46) standard. It is similar to tr46 in that it handles internationalized domain names, but it may have different API options and compliance specifics.
