Is the problem with utoa() not generating the string, or the inability to display a correct string?

It is not printing anything i think its problem with utoa()

it is how I have used utoa() function

Unicode::utoa(FrequencyStruct.period, mBuf, 4, 10);

periodValueTxt.setWildcard(mBuf);

Perhaps use a debugger and make an actual determination.

Is the buffer deep enough to hold potential outputs with NUL termination?
