Subject of the issue

I try to playing animate

Steps to Reproduce

I'm try to run animate character with font arabic and roman. step 1 : call P.displayAnimate to text with effect PA_SCROLL_RIGHT no issue. step 2 : but once the call P.displayAnimate to text with effect FADE there is issue. and issue on Exception Decoder. then try investigate the issue to EPS exception decoder. path issue is 0x4020c4e5: MD_PZone::commonPrint() at libraries\MD_Parola\src\MD_Parola_Print.cpp line 47

sorry my english is basic.

The text buffer must persist while the animation is being completed. In the case where you are using the c_Str conversion for a String this is unlikely to be the case.

The text buffer must persist while the animation is being completed. In the case where you are using the c_Str conversion for a String this is unlikely to be the case.

Can we adjust the setTextBuffer to null or ""?

[MajicDesigns]

You should adjust to a valid c-string that remains in scope while the animation is active.
