--- Comment #3 from Taylor <taylorleebiz at gmail.com> ---
Using http://www.unicode.org/Public/UNIDATA/UnicodeData.txt as reference, we
can grep for ';(Cc|Cn);'.

We find that Cc and Cn chars are:
0x00 to 0x1F (inclusive)
0x7F to 0x9F (inclusive)

Using the above info, we can update the CLEAN isPrintable() function.

I also added CLEAN.OOXML using a new isPrintable_OOXML() function that returns
true only if c > 0x1f.

Using the following fods to verify, I found that the CHAR function is not
appropriate to use with CLEAN since CHAR returns 0xfffd for the range of 0x80
to 0xFF inclusive.  0x100 and above returns Err:502.

core/sc/qa/unit/data/functions/text/fods/clean.fods

Changing CHAR to UNICHAR, we can then successfully test the range 0x80 to 0x9F.

I'll attempt to use gerrit to start the patch process.
