Symbols related to Black Triangle Up
These are filed under up-pointing, triangle and arrow in CLDR, the keyword list Unicode publishes alongside the names.
Other symbols
Black Triangle Up is not the only name it goes by: people look for ▲ as play too, and the search box on this site matches that as readily as the Unicode name.
▲ lives in the Geometric Shapes block (U+25A0-U+25FF), squares, circles, triangles and diamonds. Within Unicode it is classified as So, a symbol.
What Black Triangle Up is used for
In mathematical notation ▲ is an ordinary symbol: it carries no special spacing and sits in an expression the way a letter does, standing for a thing rather than doing something to the things around it. That is the classification unicode-math gives it, and it is what decides how the symbol is set: $\bigblacktriangleup$ in LaTeX, in maths mode rather than in a sentence.
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 filled up-pointing triangle and arrow. Those words are what somebody looking for this character is liable to type when Black Triangle Up 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 Black Triangle Up
The code chart points from ▲ to black medium up-pointing triangle (U+23F6), black medium up-pointing triangle centred (U+2BC5) and up-pointing red triangle (U+1F53A). These are the characters the standard thinks you might have meant instead, which makes them the ones worth checking when Black Triangle Up looks nearly right but not quite.
How Black Triangle Up 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.

If ▲ arrives as â–²
One character has become three, which is what a three-byte UTF-8 sequence looks like when each byte is read separately: E2 96 B2 read as Windows-1252 gives exactly â–². The text is intact and the damage is in the reading, so setting the reader to UTF-8 restores it and retyping does not. A rectangle instead of the mojibake means the opposite: the encoding is right and the font has no glyph at U+25B2, which for a character this far outside Latin-1 is common in older office fonts.
