What ﹗ means
The punctuation stays exclamatory; only the typographic form is compact. The ordinary ! is also nicknamed a “bang” in English. ﹗ is a compact compatibility variant associated with CNS 11643, a character-encoding standard for Chinese text.
Chinese typesetting guidance sets spacing for repeated exclamation marks and punctuation strings such as !?. Japanese punctuation guides use fullwidth ! as the ordinary mark. These are layout conventions around exclamation punctuation.
