Error in clrCall(obj, "HighLightText", text): System.ArgumentOutOfRangeException

[brooksambrose]

First, thanks for a very cool utility, I haven't found anything else quite like it.

I have found that some words seem to cause an error, and I can't see a pattern. Here's an example file that works when highlighting the word "programs" but throws an error for the word "Programs".

2020-04InstConn-pst.pdf

Do you have a clue why some words would cause an error and others don't?

> pdfUtils::Highlightext('rClr','2020-04InstConn-pst.pdf','programs')
Text highlighted successfully.
> pdfUtils::Highlightext('rClr','2020-04InstConn-pst.pdf','Programs')
