Resources data cleaning

Data is easier to process and search if it's tidy.

Manual QA:

Sort A-Z and Z-A by each of the columns, see if anything is missing or inconsistent.
Are there any "null"s that shouldn't be nulls?
Run it through a broken link checker - are there any broken links?
Are there any HTTP links? All links should be HTTPS.
Check for links to non-.gov websites. Is it a legitimate government website or publication? For example, is it an official CMS site run by contractors, such as PASRR Technical Assistance Center or ResDAC?

Remove:

Duplicate items (multiple items with the same URL)
Hidden Unicode control characters
Newlines
Double spaces

Consider whether to systematically re-process:

Curly quotes
Curly apostrophes ’
Em dashes and en dashes — (may also need to make sure they have spaces around them, to ensure searchability)
Copyright and registered trademark symbols ®
Section symbols
