+/**
+ * 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
+ * - mb_preferred_mime_name - Get MIME charset string
+ * - mb_regex_encoding - Returns current encoding for multibyte regex as string
+ * - mb_regex_set_options - Set/Get the default options for mbregex functions
+ * - mb_send_mail - Send encoded mail
+ * - mb_split - Split multibyte string using regular expression
+ * - mb_strcut - Get part of string
+ * - mb_strimwidth - Get truncated string with specified width
