Overview

Single element from the UCDXML flat file.

UCDXML uses two forms:

<char cp="0041" name="..." script="Latin" block="Basic Latin" .../>
<char first-cp="3400" last-cp="4DBF" name="..." script="Han" .../>

The first form describes one codepoint. The second form describes a closed range of codepoints that share the same properties (used for CJK ideograph ranges where each codepoint would otherwise need its own entry).

Both forms can appear in the same document; cp is mutually exclusive with first-cp/last-cp.

Instance Method Details

#codepoints ⇒ Object

The codepoints covered by this entry, as Integers. For a single-codepoint entry, returns a one-element array. For a range entry, returns the inclusive range as an array (caller should treat this lazily if the range is huge — CJK ranges can have tens of thousands of codepoints).
