Zero-width space

	Why doesn't this in UCdomap.c:

	else if (ucs == 0xfeff || (ucs >= 0x200b && ucs <= 0x200f)) { 
        /*
         * Zero-width space.
         */
        return ucZeroWidth;

cause 200b (zero-width space, aka 8203) to be undisplayed?


	It seems to make this in LYCharUtils.c :

       /*
                 * Ignore 8204 (zwnj), 8205 (zwj) 8206 (lrm), and 8207 (rlm),
                 * for now, if we got this far without finding a representation
                 * for them.
                 */
            } else if (code == 8204 || code == 8205 ||
                       code == 8206 || code == 8207) {
                CTRACE((tfp, "LYUCFullyTranslateString: Ignoring '%"
                        PRI_UCode_t "'.\n", CAST_UCode_t (code)));
                replace_buf[0] = '\0';
                state = S_got_outstring;
                break;


unnecessary.  And why does it neglect 8203?

	8203 appears in https://www.newyorker.com/news/the-lede/the-democratic-party-rebrands-itself-before-viewers-eyes
