If you are able to write the text file in any format you need, one possibility would be to write it as an XML WordProcessingML file in "Flat OPC format" that Word should treat as a Word document.
What you do is start with a "minimal document". The first chunk of the file looks like this (you should not need to change anything):
<?xml version='1.0' encoding='UTF-8'?>
<pkg:package xmlns:pkg='http://schemas.microsoft.com/office/2006/xmlPackage'>
<pkg:part pkg:name='/_rels/.rels'
pkg:contentType='application/vnd.openxmlformats-package.relationships+xml'>
<pkg:xmlData>
<Relationships xmlns='http://schemas.openxmlformats.org/package/2006/relationships'>
<Relationship Id='rid1'
Type='http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument'
Target='word/document.xml'/>
</Relationships>
</pkg:xmlData>
</pkg:part>
<pkg:part pkg:name='/word/document.xml'
pkg:contentType='application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml'>
<pkg:xmlData>
<w:document xmlns:w='http://schemas.openxmlformats.org/wordprocessingml/2006/main'>
<w:body>
The last part of the file looks like this:
</w:body>
</w:document>
</pkg:xmlData>
</pkg:part>
</pkg:package>
Between those two predefined pieces, you need to put your data. There are various ways you can do that, but there's no real reason not to stick to "CSV" format. So if you have a data source like this:
key,text
1,"mytext1"
2,"mytext2"
then the XML would need to look like this:
<w:p><w:r><w:t>key,text</w:t></w:r></w:p>
<w:p><w:r><w:t>1,"mytext1"</w:t></w:r></w:p>
<w:p><w:r><w:t>2,"mytext2"</w:t></w:r></w:p>
If you have the characters "&" or "<" in the data, you have to "escape" them - in essence, instead of "&" use & and instead of "<" use <
As for "unicode" characters, you can either insert the appropriate UTF-8 byte sequence or use, say "�" format so you could insert "Greek Small Letter Alpha" using "α"
