unicode characters in html

I would like to display characters from this table, http://www.tamasoft.co.jp/en/general-info/unicode.html, in my html-page. For example, the tiny downward arrow that sits in the table at 25A0 1F. I've tried �, and � both do not work. What do I need to write in my html-document?

I'm using:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

You're misreading the table: You have to add the column head to the row head: ▿

The table rows are labelled in multiples of 32, and the columns are the remainder modulo 32.

Yes you have too many decimals for a hexadecimal character. You might try using this site. It has a bunch of handy UTF-8 characters (arrows and pictograms) and you don't have to line up a chart. Just click and it will be copied to your pasteboard.

Or much easier way to find and get html, css or unicode:

Or just use search tool.
