Edit:Just noticed that below my input window it said that I don't need to use HTML entities in code blocks and could use the literal characters. That's obviously not the case.

Could you change the code blocks to retain the user's original input? The worst offender is when one uses unicode. Example: If I include the greek pi (π) in regular text like this, it displays properly @ render time even though it was converted to an HTML entity (like &#960).

However, if it is a code block, something still modifies my formatting/input and changes my code to use an entity too, but then, to compound the problem, because it is a code block, it doesn't get reprocessed back into a UTF-8 character, but remains as an HTML entity, like:

This pi (π) doesn't display correctly.

I would argue that because it is a code block, it should have >not< turned it into an HTML entity in the first place. Then it would display properly at page-render time. While it would be acceptable if it at least was 'round-trip safe' and displayed it correctly @ render time, it seems that it would be more correct or more 'ideal' to not touch the user's input in the 1st place in a code block.

Since it displays correctly in regular text, it should at least be possible to get it to display right in a code block, but no one would know that the author used the correct character to begin with.

Thanks...
