text formatting not the same once text saved

My plain text in the editor changes after it is saved. How do i fix this.
eg E′noch becomes E?noch (with a question mark.)

copied into editor;
(Luke 3:36-38) . . .[son] of Shem, [son] of Noah, [son] of La′mech, 37 [son] of Me·thu′se·lah, [son] of E′noch, [son] of Ja′red, [son] of Ma·ha′la·le·el, [son] of Ca·i′nan, 38 [son] of E′nosh, [son] of Seth, [son] of Adam, [son] of God. is the plain text copied into editor.

after save it appears as;
(Luke 3:36-38) . . .[son] of Shem, [son] of Noah, [son] of La?mech, 37 [son] of Me·thu?se·lah, [son] of E?noch, [son] of Ja?red, [son] of Ma·ha?la·le·el, [son] of Ca·i?nan, 38 [son] of E?nosh, [son] of Seth, [son] of Adam, [son] of God.

i have created a test page to show the result.
