Does the same thing happen when you select to add new text using this font (vs. editing existing text)? Based on the screen shot, it looks like you are using Acrobat XI. Right under the "Edit text & Images" tool is the "Add Text" tool. Select that, then change your font selection and then click anywhere in your PDF file and start to type new text. Does it show up correctly? If it does, then there is very likely a mismatch between the encoding used for the text in your document and the encoding used in the new font. Can you edit the original text using a different font?
