Q -

Windows CharMap can be used to copy and paste them. They do appear in Arial and Times New Roman on my machine at least.

In recent versions of Word, you can type 0108 and 0109, and hit Ctl-X before typing anything following, and they'll convert to the U0108 (upper case) Ĉ and U0109 (lower case) ĉ letters. Copy and paste from there.

Of course, people here will only see them if they're using a "proper" font for viewing.
