Character set table for unicode conversion

Question

Experts,
If one identifies a special character that fails during code page conversion (CX_SY_CONVERSION_CODEPAGE), can this character then be added into a table that will recongnize it and not fail moving forward? If so, how to go about it?
Any help is appreciated.

Note this
Unicode Error : In the Unicode context, TRANSLATE... CODEPAGE/NUMBER FORMAT is not allowed.
Before Unicode
TRANSLATE T143T-TBTXT FROM CODE PAGE '1100' TO CODE PAGE '1105'.
After Unicode
Use class for Translate codepage to codepage.
Data : g_codepage LIKE tcp0c-charco VALUE '1100'.
CONSTANTS: c_unicodecp(4) VALUE '1105'.
PERFORM translate_codepage USING g_codepage
