Currently if a search term in the PDF text has been broken over two lines by a soft hyphen, find will not correctly identify it as a match. This is rooted in the fact that the result of FPDF_GetText includes a marker for soft-hyphens, 0xFFFE, which causes the match to fail. This CL adds in filtering this character from the text being searched over, so that these matches can pass. This requires changes in the SearchUsingICU method to strip ignorable characters from the string before searching, and correctly converting the results back into the non-stripped index space. Ranges also have had filtering for 0xFFFE added in, so that the highlights created by searching are properly placed.
