tdf#113483: DOCX: fix encoding of bookmarks with non-ASCII letters

Non-ASCII letters were stored using percent-encoding, resulting
broken bookmark names after export/import. For example, the word "Első"
became the wrong "Els%C5%91". Now only the reversed ASCII characters
are stored in percent-encoding.

For example, the name "Első!" stored in the following form:

<w:bookmarkStart w:name="Első%21" w:id="0"/>
<w:instrText> REF Első%21 \h </w:instrText>
