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 Lu, an uppercase letter. It has a lowercase counterpart and changes under case conversion. Its bidirectional class makes it left-to-right.
Its lowercase counterpart is ø (U+00F8). 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 Capital 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.
The code chart points from Ø to Empty Set, latin capital letter o with middle tilde (U+019F) and latin capital letter o with long stroke overlay (U+A74A). These are the characters the standard thinks you might have meant instead, which makes them the ones worth checking when Capital O with Stroke looks nearly right but not quite.
How Capital 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 98 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+00D8.
