To box the whole 'word' containing the ChrW(9700), you could use:
Code:
Sub Demo()
Application.ScreenUpdating = False
With ActiveDocument.Range
With .Find
.ClearFormatting
.Replacement.ClearFormatting
.Text = "[aeiouy]" & ChrW(9700) & "[bcdfghjklmnpqrstvwxyz]*>"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindStop
.Format = False
.MatchWildcards = True
.Execute
End With
Do While .Find.Found
.Start = .Words.First.Start
.Borders.Enable = True
.Collapse wdCollapseEnd
.Find.Execute
Loop
End With
Application.ScreenUpdating = True
End Sub
To box just the "vowel" & ChrW(9700) & "consonant", you could use the above without the '*>' and '.Start = .Words.First.Start'.
