Chinese Script in HKEY_Current_user

I have the following in my registry and I want to know if it harmful or what it is exactly. This is fairly new appeared since my last examination of the registry.

The reason I searched the registry is because my pc will not delete past search terms regardless of how many times I clear search history and It reloads Bing regardless of the fact that I repeatedly select 2 other search search engines as default search engines and save them as default search engines.

Also, pages are slow to load and the deleted internet search history shows up in a drop down box when I try and use the facebook search feature. The search history text in the drop down box that appear on facebook is NOT anything I searched for on Facebook such as a business or my online bank website, amazon and searches for factual information that I would want to find on wikipedia or any other reference matwerial site.

I have purchased Avast and a malware detecytion and removal software but enither show that there is anything amiss. Thank you!

This is a Chinese UTF-8-Unicode-Test-Document and quite harmless.

I just found this in my registry as well. Used Google translate on HKEY_CURRENT_USER\潣⹭癡獡⹴灩⹭汃敩瑮慐慲敭整獲䰮捯污啥敳䑲晥畡瑬 (without spaces) and it says “I’m so stupid, I’ve got a lot of scumbags”
Google also showed this “Mǐn chī shuò yàn bīn xiào lì gong mán yáng zhěng huò 䰮 dáo wū shà ái zhào wǎn gāi liú”
which says"A person who wants to know what he wants is to be happy. He wants to be happy. He wants to be happy."
So that is kinda strange.
Other online translators say various things.
I used BING translate and it thought this was Japanese and said “The fish is the first to be able to capture the fish.”
I told BING to try Chinese and it translated it to “What’s the whole thing?”
Not sure what to make of this?
Not much to be found on the inter-webs about it either. :o
