MetaImage seems to only read up to two hundred characters from the IPTC Headline (ref2017.1) field. I created a test image with this text in the field:
Far far away, b(15)ehind the word (30)mountains, far (45)from the countr(60)ies Vokalia and(75) Consonantia, t(90)here live the b(105)lind texts. Sep(120)arated they liv(135)e in Bookmarksg(150)rove right at t(165)he coast of the(180) Semantics, a l(195)arge language o(210)cean. A small r(225)iver named Dude(240)n flows by thei(255)r place and sup(270)plies it with t(285)he necessary re(300)gelialia. It is(315) a paradisemati(330)c country, in w(345)hich roasted pa(360)rts of sentence(375)s fly into your(390) mouth. Even th(405)e all-powerful (420)Pointing has no(435) control about (450)the blind texts(465) it is an almos(480)t unorthographi(495)c life One day (510)however a small(525) line of blind (540)text by the nam(555)e of Lorem Ipsu(570)m decided to le(585)ave for the far(600) World of Gramm(615)ar. The Big Oxm(630)ox advised her (645)not to do so, b(660)ecause there we(675)re thousands of(690) bad Commas, wi(705)ld Question Mar(720)ks and devious (735)Semikoli, but t(750)he Little Blind(765) Text didn’t li(780)sten. She packe(795)d her seven ver(810)salia, put her (825)initial into th(840)e belt and made(855) herself on the(870) way. When she (885)reached the fir(900)st hills of the(915) Italic Mountai(930)ns, she had a l(945)ast view back o(960)n the skyline o(975)f her hometown (990)Bookmarksgrove,(1005) the headline o(1020)f Alphabet Vill(1035)age and the sub(1050)line of her own(1065) road, the Line(1080) Lane.

This is what displays in MetaImage:
