|ext:convert-bytes-to-string iconv-desc bytes head available string start requested||[Function]|
Convert the foreign character bytes, starting at offset head and using at most the available bytes, directly into a native string at offset start and for up to the requested number of characters. The character conversion is determined by the iconv-desc. The number of bytes consumed and the number of characters written to the string are returned. The conversion stops at the first conversion error, and the error will be signaled if it occurs at the first byte otherwise a partial conversion is returned.
