Characters that don't exist in the target char set are difficult to convert. The -c option would not necessarily help as it just silently deletes inconvertible chars.
Not sure what your OS / shell / iconv versions are. Does the latter offer this option (man iconv)
Quote:
-t to-encoding, --to-code=to-encoding
Use to-encoding for output characters.
. . .
If the string //TRANSLIT is appended to to-encoding, characters being converted are transliterated when needed and possible. This means that when a character cannot be represented in the target character set, it can be approximated through one or several similar looking characters. Characters that are outside of the target character set and cannot be transliterated are replaced with a question mark (?) in the output.
? Would his come close to what you need?

iconv_open

ICONV_OPEN(3)						     Linux Programmer's Manual						     ICONV_OPEN(3)

NAME

       iconv_open - allocate descriptor for character set conversion

SYNOPSIS

       #include <iconv.h>

       iconv_t iconv_open(const char *tocode, const char *fromcode);

DESCRIPTION

       The  iconv_open()  function  allocates  a  conversion descriptor suitable for converting byte sequences from character encoding fromcode to
       character encoding tocode.

       The values permitted for fromcode and tocode and the supported combinations are system-dependent.  For the GNU  C  library,  the  permitted
       values  are listed by the iconv --list command, and all combinations of the listed values are supported.  Furthermore the GNU C library and
       the GNU libiconv library support the following two suffixes:

       //TRANSLIT
	      When the string "//TRANSLIT" is appended to tocode, transliteration is activated.  This means that when a character cannot be repre-
	      sented in the target character set, it can be approximated through one or several similarly looking characters.

       //IGNORE
	      When the string "//IGNORE" is appended to tocode, characters that cannot be represented in the target character set will be silently
	      discarded.

       The resulting conversion descriptor  can  be  used  with  iconv(3)  any	number	of  times.   It  remains  valid  until	deallocated  using
       iconv_close(3).

       A conversion descriptor contains a conversion state.  After creation using iconv_open(), the state is in the initial state.  Using iconv(3)
       modifies the descriptor's conversion state.  (This implies that a conversion descriptor can not be  used  in  multiple  threads	simultane-
       ously.)	To bring the state back to the initial state, use iconv(3) with NULL as inbuf argument.

RETURN VALUE

       The iconv_open() function returns a freshly allocated conversion descriptor.  In case of error, it sets errno and returns (iconv_t) -1.

ERRORS

       The following error can occur, among others:

       EINVAL The conversion from fromcode to tocode is not supported by the implementation.

VERSIONS

       This function is available in glibc since version 2.1.

       UNIX98, POSIX.1-2001.
