Has anyone already mentioned Alt 0226 - â also 0234 ê
I can’t remember how to assign these to actual keys on the keyboard, so you don’t have to remember the numbers, but you can do that or you used to be able to program some of the keys to be whatever you wanted them to be.
I suspect these tips have all been done before, but just in case here is a link to lots of useful Welsh and Cornish codes and tips for doing things in lots of different ways - includes Middle Welsh characters as well!

Also go to http://www.interceptorsolutions.com/user-guide and download a free Tô bach utility or create your own:
Step 1: Download Autohotkey from https://autohotkey.com/ and run the exe file: (Note: looks fine to me, but at your own risk).
Step 2: Right Click on desktop: then scroll to New: then scroll to Autohotkeyscript
Step 3: An icon will appear on the desktop. Change the file name to whatever you prefer.
Step 4: Right click on the icon and then click edit.
Step 5: Notepad should open. Delete the text in the note pad file.
Step 6: paste this string into the notepad file:
!+a::
Send, â
Return
!+e::
Send, ê
Return
!+i::
Send, î
Return
!+o::
Send, ô
Return
!+u::
Send, û
Return
!+w::
Send, ŵ
Return
!+y::
Send, ŷ
Return
Step 7: save the file
Step 8: click on it and it will now be active.
shift + alt + vowel gives the following:
â ê î ô û ŵ ŷ
