I wanted to create a new User Tool "Didache" in Latvian. So I created "Didahe (Latviski)" User Tool and tried to paste Unicode text from this web page: http://biblos.lv/Didahe.html(Reader Mode in Safari browser), but it pasted only first 2-3 words and that's all.
Then I saved Didache e-text as HTML, opened it in TextEdit, removed image and simplified formatting. Tried to import saved HTML file into the existing User Tool file. It imported all text, except all Latvian letters were lost. I opened file for editing, but it doesn't even show Unicode characters properly when I enter them. Can't type in Latvian. A bug or a missing feature?
