* - Adds the `XRegExp.addUnicodeData` method used by other addons to provide character data.

* Adds to the list of Unicode tokens that XRegExp regexes can match via `\p` or `\P`.

|
*
|
|
* @memberOf XRegExp
|
|
* @param {Array} data Objects with named character ranges. Each object may have properties
|
|
* `name`, `alias`, `isBmpLast`, `inverseOf`, `bmp`, and `astral`. All but `name` are
|
|
* optional, although one of `bmp` or `astral` is required (unless `inverseOf` is set). If
|
|
* `astral` is absent, the `bmp` data is used for BMP and astral modes. If `bmp` is absent,
|
|
* the name errors in BMP mode but works in astral mode. If both `bmp` and `astral` are
|
|
* provided, the `bmp` data only is used in BMP mode, and the combination of `bmp` and
|
|
* `astral` data is used in astral mode. `isBmpLast` is needed when a token matches orphan
|
|
* high surrogates *and* uses surrogate pairs to match astral code points. The `bmp` and
|
|
* `astral` data should be a combination of literal characters and `\xHH` or `\uHHHH` escape
|
|
* sequences, with hyphens to create ranges. Any regex metacharacters in the data should be
|
|
* escaped, apart from range-creating hyphens. The `astral` data can additionally use
|
|
* character classes and alternation, and should use surrogate pairs to represent astral code
|
|
* points. `inverseOf` can be used to avoid duplicating character data if a Unicode token is
|
|
* defined as the exact inverse of another token.
|
|
* @example
|
|
*
|
|
* // Basic use
|
|
* XRegExp.addUnicodeData([{

* name: 'XDigit',

|
* alias: 'Hexadecimal',
|
|
* bmp: '0-9A-Fa-f'
