+/**
+ * Calculate the physical width of a string in a TTY-like environment. This is
+ * useful for cases such as calculating where a line-wrap will occur and
+ * underlining strings.
+ *
+ * The physical width is given by the number of columns required to display
+ * the string. The number of columns a given unicode character occupies can
+ * vary depending on the character itself.
+ *
+ * @param str The string to measure.
+ * @returns The unicode width of the string.
+ *
+ * @example Calculating the unicode width of a string
+ * ```ts
+ * import { unicodeWidth } from "https://deno.land/std@$STD_VERSION/cli/unicode_width.ts";
+ *
+ * unicodeWidth("hello world"); // 11
+ * unicodeWidth("天地玄黃宇宙洪荒"); // 16
+ * unicodeWidth("ｆｕｌｌｗｉｄｔｈ"); // 18
+ * ```
+ *
+ * @example Calculating the unicode width of a color-encoded string
+ * ```ts
+ * import { unicodeWidth } from "https://deno.land/std@$STD_VERSION/cli/unicode_width.ts";
+ * import { stripAnsiCode } from "https://deno.land/std@$STD_VERSION/fmt/colors.ts";
+ *
+ * unicodeWidth(stripAnsiCode("\x1b[36mголубой\x1b[39m")); // 7
+ * unicodeWidth(stripAnsiCode("\x1b[31m紅色\x1b[39m")); // 4
+ * unicodeWidth(stripAnsiCode("\x1B]8;;https://deno.land\x07🦕\x1B]8;;\x07")); // 2
+ * ```
+ *
+ * Use
+ * {@linkcode https://jsr.io/@std/fmt/doc/colors/~/stripAnsiCode | stripAnsiCode}
+ * to remove ANSI escape codes from a string before passing it to
+ * {@linkcode unicodeWidth}.
