The CH beta website has an issue (I've reported there also) with HTML escaping of some characters in company names in the search list pages. (This doesn't affect the API which reports the underlying data correctly in both).
08264580 named M&M PARTY PACKS "EXCLUSIVE PARTY SOLUTIONS" LTD
Shows as M&M PARTY PACKS "EXCLUSIVE PARTY SOLUTIONS" LTD in search but M&M PARTY PACKS "EXCLUSIVE PARTY SOLUTIONS" LTD (correct) in profile.
11678385 - BETTS & TWINE LTD appears as BETTS & TWINE LTD
07657267 - JW INSTALLATIONS & TEST LIMITED appears as JW INSTALLATIONS & TEST LIMITED in search.
09040187 - MISTER SINCLAIR FITNESS & WELLBEING LIMITED appears as MISTER SINCLAIR FITNESS & WELLBEING LIMITED

There is 7074667 - ASPIRE CHILDREN&APOS;S SERVICES LIMITED - which appears correctly in both (' was not in HTML4 but apparently in HTML5 and possibly XHTML / some XML?).
