- When converting an ICU date/time format to PHP, text within single quotes will be replaced with backslashes in front of each character (the PHP date() method for escaping text), and double-single quotes will be replaced with single quotes.
- When converting an ICU date/time format to jQuery UI, text within single quotes, and double-single quotes, will each be preserved (rather than parsed for date/time format symbols), as jQuery UI uses the same text escaping and single quote syntax as ICU.
- Add support for '' within 'escaped text' E.g. 'o''clock'
