While most common Unicode values can be represented using one 16-bit unit, higher code point characters require two 16-bit units (a surrogate pair consisting of a high and a low surrogate) to form a single character. [`String.fromCharCode`][mdn-string-fromcharcode] does **not** support surrogate pairs, supporting only UCS-2, a subset of [UTF-16][utf-16].\n\n-   This function differs from [`String.fromCodePoint`][mdn-string-fromcodepoint] in the following ways:\n\n    -   The function supports explicitly providing an array-like `object` containing a sequence of [code points][code-point].\n    -   The function requires **at least** one [code point][code-point].\n    -   The function requires that all [code points][code-point] be nonnegative integers. The function does **not** support values, such as `null`, `undefined`, `true`, `false`, `'0'`, `'1'`, etc., which can be cast to integer values.\n\n\u003c/section\u003e\n\n\u003c!-- /.notes --\u003e\n\n\u003c!-- Package usage examples. --\u003e\n\n\u003csection class=\"examples\"\u003e\n\n## Examples\n\n\u003c!-- eslint no-undef: \"error\" --\u003e\n\n```javascript\nvar randu = require( '@stdlib/random-base-randu' );\nvar floor = require( '@stdlib/math-base-special-floor' );\nvar UNICODE_MAX_BMP = require( '@stdlib/constants-unicode-max-bmp' );\nvar fromCodePoint = require( '@stdlib/string-from-code-point' );\n\nvar x;\nvar i;\n\nfor ( i = 0; i \u003c 100; i++ ) {\n    x = floor( randu()*UNICODE_MAX_BMP );\n    console.log( '%d =\u003e %s', x, fromCodePoint( x ) );\n}\n```\n\n\u003c/section\u003e\n\n\u003c!-- /.examples --\u003e\n\n\u003c!-- Section for describing a command-line interface. --\u003e\n\n* * *\n\n\u003csection class=\"cli\"\u003e\n\n## CLI\n\n\u003csection class=\"installation\"\u003e\n\n## Installation\n\nTo use as a general utility, install the CLI package globally\n\n```bash\nnpm install -g @stdlib/string-from-code-point-cli\n```\n\n\u003c/section\u003e\n\u003c!-- CLI usage documentation. --\u003e\n\n\n\u003csection class=\"usage\"\u003e\n\n### Usage\n\n```text\nUsage: from-code-point [options] [\u003ccode_point\u003e \u003ccode_point\u003e ...]\n\nOptions:\n\n  -h,    --help                Print this message.\n  -V,    --version             Print the package version.\n         --split sep           Delimiter for stdin data.
