Other accents symbols
ø 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 Ll, a lowercase letter. It has an uppercase counterpart and changes under case conversion. Its bidirectional class makes it left-to-right.
Its uppercase counterpart is Ø (U+00D8). They are separate codepoints, so a byte comparison treats them as different characters even though a case-insensitive search does not.
What Unicode says about O with Stroke
The standard recognises ø under another name as well: o slash. That is a formal alias, not a nickname, which is why it turns up in other people's documentation for the same codepoint.
Unicode annotates ø directly. Against U+00F8 the code chart carries the note “Danish, Norwegian, Faroese, IPA”. That is the standard saying what the character is for, rather than an inference from its name.
The code chart points from ø to latin small letter barred o (U+0275), diameter sign (U+2300), latin small letter o with long stroke overlay (U+A74B), latin small letter old polish o (U+A7C1) and latin small letter blackletter o with stroke (U+AB3E). These are the characters the standard thinks you might have meant instead, which makes them the ones worth checking when O with Stroke looks nearly right but not quite.
How O with Stroke behaves in software
ø 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 is a left-to-right character, so it holds that direction even inside a right-to-left paragraph.

If ø arrives as ø
That is this exact character, undamaged: its two UTF-8 bytes C3 B8 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+00F8.
