Hi, on SHC 205002233
     running 13.1.0 for XO-1.75 (build 20)
     with Sugar 0.98.2
     firmware Q4D24

For Text in both Write and Turtle Art (the Title panel):
     vowel + altgr - gives the Combining Macron, i.e. two bkspcs to 
remove the letter
But if either Activity is saved to the Journal and we write into its 
Description panel
     vowel + altgr - gives the Unicode version, i.e. one bksp removes 
the letter.

So we do have the right behavior in there somewhere.
