Hi Sary,

Can you see the characters in the source file ok?  Perhaps this is just a font mapping isue which you can correct.  There is some advice in the SDL KB as follows:

• Corrupt characters in the target file:

• Make sure that the target language is actually supported by SDL Trados Studio
• Make sure that the selected output encoding is set correctly via File > Active Document Settings from the menu bar in the Editor view
• Check the fonts in the file
  • Ensure that the defined target fonts are installed on your machine
  • Verify the font mapping settings via Tools > Options > File Type > your relevant file format > Font Mapping
  • Check if the use of bold, italic, underlined, superscript and so on is supported by the target font
  • Ensure the selected code page is supported by the target font
  • Check if "older" fonts are being used, like PostScript, Subtopic and TrueType fonts
• Make sure that any of your customised processing (for example via Batch Tasks) is aware of specific encoding settings
• Try to use a different target encoding via File > Active Document Settings from the menu bar in the Editor view
  • Typically Unicode works best
  • Check if the selected codepage supports all characters used in the translation
• Check that the correct code point is used in the output
  • Use the Advanced view in Windows Character Map to find the correct code point for the target font and code page
