Special Characters in text fields are not extracted

Error : 

Special characters contained in SAP table fields are not visible in Xtract Universal and may appear as '#' (hash) symbols in SAP. Attached screenshots for reference. 

Example:
SAP data returned by RFC_READ_TABLE : 170D1A012073;ELIT;01;Performance ADv.Jan_2010_8,50#
Preview in Xtract Universal: 170D1A012073    ELIT   01     Performance ADv.Jan_2010_8,50

Reason :
This behavior is not caused by Xtract Universal. Xtract Universal processes the data returned by SAP via RFC_READ_TABLE. Invalid or unsupported characters (e.g. Unicode control characters) are omitted in Xtract Universal, see https://en.wikipedia.org/wiki/List_of_Unicode_characters

According to SAP KBA 2736829 - Special Characters Displayed as Hash (#) in Print Preview or PDF Output, SAP may replace unsupported or non-convertible characters with # due to issues related to:
- Unicode handling
- Font conversion
- Device types
- TrueType font configuration
- Code page conversion
- SE73 font settings
- Missing Unicode-capable fonts

Solution : Correct the affected text fields in SAP by replacing the invalid or unsupported characters with valid values. After updating the data, the characters are available in Xtract Universal.
