What 헤 means
A lone 헤 reads as mild amusement. In electronic messages, it can act as a light amused interjection; the surrounding Korean decides whether that reading fits.
Is 헤 a word or a syllable?
It is a syllable block and can also act as an interjection. Hangul groups letters into syllable blocks: 헤 combines the consonant letter ㅎ and the vowel letter ㅔ. King Sejong created the script in 1443, and its explanatory book appeared in 1446. It gave Korean speakers a way to write their language without relying on Chinese characters.
Light and informal.
Inside a longer word, 헤 is one syllable; do not automatically read it as laughter.

1Why does 헤 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
