-/**

- * Partial mbstring implementation in PHP, iconv based, UTF-8 centric.

- *

- * Implemented:

- * - mb_chr                  - Returns a specific character from its Unicode code point

- * - mb_convert_encoding     - Convert character encoding

- * - mb_convert_variables    - Convert character code in variable(s)

- * - mb_decode_mimeheader    - Decode string in MIME header field

- * - mb_encode_mimeheader    - Encode string for MIME header XXX NATIVE IMPLEMENTATION IS REALLY BUGGED

- * - mb_decode_numericentity - Decode HTML numeric string reference to character

- * - mb_encode_numericentity - Encode character to HTML numeric string reference

- * - mb_convert_case         - Perform case folding on a string

- * - mb_detect_encoding      - Detect character encoding

- * - mb_get_info             - Get internal settings of mbstring

- * - mb_http_input           - Detect HTTP input character encoding

- * - mb_http_output          - Set/Get HTTP output character encoding

- * - mb_internal_encoding    - Set/Get internal character encoding

- * - mb_list_encodings       - Returns an array of all supported encodings

- * - mb_ord                  - Returns the Unicode code point of a character

- * - mb_output_handler       - Callback function converts character encoding in output buffer

- * - mb_scrub                - Replaces ill-formed byte sequences with substitute characters

- * - mb_strlen               - Get string length

- * - mb_strpos               - Find position of first occurrence of string in a string

- * - mb_strrpos              - Find position of last occurrence of a string in a string

- * - mb_str_split            - Convert a string to an array

- * - mb_strtolower           - Make a string lowercase

- * - mb_strtoupper           - Make a string uppercase

- * - mb_substitute_character - Set/Get substitution character

- * - mb_substr               - Get part of string

- * - mb_stripos              - Finds position of first occurrence of a string within another, case insensitive

- * - mb_stristr              - Finds first occurrence of a string within another, case insensitive

- * - mb_strrchr              - Finds the last occurrence of a character in a string within another

- * - mb_strrichr             - Finds the last occurrence of a character in a string within another, case insensitive

- * - mb_strripos             - Finds position of last occurrence of a string within another, case insensitive

- * - mb_strstr               - Finds first occurrence of a string within another

- * - mb_strwidth             - Return width of string

- * - mb_substr_count         - Count the number of substring occurrences

- *

- * Not implemented:

- * - mb_convert_kana         - Convert "kana" one from another ("zen-kaku", "han-kaku" and more)

- * - mb_ereg_*               - Regular expression with multibyte support

- * - mb_parse_str            - Parse GET/POST/COOKIE data and set global variable
