+## Abstract
+
 convbkmk is a tiny utility for making correct bookmarks in pdf files
 typesetted by platex/uplatex with the hyperref package.
 platex/uplatex + hyperref outputs data of bookmarks
 in their internal encodings (EUC-JP, Shift_JIS or UTF-8).
 On the other hand, the PostScript/PDF format requests that
-the data is written in a certain syntax with UTF-16 or PDFDocEncoding.
+the data are written in a certain syntax with UTF-16 or PDFDocEncoding.
 Thus, data conversion is required to create correct bookmarks.
 convbkmk provides a function of
 the encoding conversion and formatting the bookmark data.
