Unused CJK fonts get inside of text documents with embedded fonts, which creates huge documents.
Steps to Reproduce:
1. Create new text document
2. Check File -> Properties -> Fonts -> 'Embed fonts in the document'
3. Save file
This creates huge file (more than 20 Mb) with unused CJK fonts inside.
Embed only fonts defined in Styles or used via direct formatting.

Example test document
Build ID: 05dceb5d363845f2cf968344d7adab8dcfb2ba7
Downloaded the (empty) document => 25 MB
11 Embedded fonts:
Microsoft YaHei bold => 9,4 MB
Microsoft YaHei UI => 13,8 MB
AR PL Sungtil GB => 2,3 MB
I opened styles.xml => the three fonts mentioned above are used in styles. So it's the expected result I would say.
