txtwrite - Bug #693046 handle TEXT_FROM_CHARS and TEXT_FROM_SINGLE_CHAR ops
I seem to have overlooked these operations when writing the original code,
probably because I couldn't' find any test cases. However PCL seems to make
extensive use of them, and the lack of code causes access outside array
boundaries.
Fixed here in a simplistic fashion, which seems to work well.
No differences expected, txtwrite is not cluster tested
