Symbols related to Inverted Exclamation
The Unicode code chart points from ¡ to !, and the rest are filed under inverted in CLDR, the keyword list Unicode publishes alongside the names.
Other punctuation symbols
¡ lives in the Latin-1 Supplement block (U+0080-U+00FF), the accented letters and common signs Western European languages needed. Within Unicode it is classified as Po, a punctuation mark.
What Inverted Exclamation is used for
¡ belongs in prose rather than in an equation. LaTeX writes it \textexclamdown, a text command, and there is no maths command for it at all: it is a sign that gets written down, not an operator that acts on anything. Putting it inside $...$ is how it comes out looking wrong.
Unicode publishes a second list of names for ¡ in CLDR, the keywords its own search data offers rather than the formal name, and they are inverted exclamation mark, bang and point. Those words are what somebody looking for this character is liable to type when Inverted Exclamation is not the name they know it by, and the search on the symbol lists matches them as well as the Unicode name.
What Unicode says about Inverted Exclamation
Unicode annotates ¡ directly. Against U+00A1 the code chart carries the note “Spanish, Asturian, Galician”. It adds: used in extended IPA to represent sublaminal lower alveolar percussive. That is the standard saying what the character is for, rather than an inference from its name.
The code chart points from ¡ to Exclamation Mark and modifier letter raised inverted exclamation mark (U+A71E). These are the characters the standard thinks you might have meant instead, which makes them the ones worth checking when Inverted Exclamation looks nearly right but not quite.
How Inverted Exclamation behaves in software
¡ is East Asian Ambiguous: one column in a Western locale and two in a CJK one. That is why a table that lines up on your machine can break on somebody else's, with no change to the text at all. It carries no direction of its own, so in a line that mixes English with Arabic or Hebrew it takes the direction of the text around it rather than forcing one.
What people ask about Inverted Exclamation
What does the exclamation point pictogram mean?
¡ is INVERTED EXCLAMATION MARK, encoded at U+00A1. The Unicode code chart annotates it “Spanish, Asturian, Galician”, which is the standard's own statement of what it is for. It is distinct from exclamation mark (U+0021) and modifier letter raised inverted exclamation mark (U+A71E), which the chart lists beside it precisely because they are confused for one another.

If ¡ arrives as ¡
That is this exact character, undamaged: its two UTF-8 bytes C2 A1 are being read one at a time as Windows-1252. The Latin-1 range is where this happens most, because it is the range every legacy system thought it already handled. Nothing is lost, and retyping will not help: the fix is at the reading end, which has to be told the text is UTF-8. An empty rectangle is the opposite complaint, and means the encoding is right and the font has no glyph for U+00A1.
