Illustrator breaks lines of Latin area type text without hyphens at arbitrary positions
It is truly a disaster. Working with packaging in different languages, I experience this problem very often. I am forced to format the text in indesign, convert it to paths and paste it into Illustrator...
Here a sample file: it seems this issue affects especially Cyrillic, but only in certain fonts.
Indesign handles it correctly.
To avoid this, I've made a script that assign the "no break" attribute to every word in a selected paragraph.

The font team informs, the font used is a Japanese font, developed by Coji Morishita. Even though it has Latin and Cyrillic glyphs in it, it’s displayed in the Japanese section in the font list, and has a preview rendered in Japanese (when no text is selected and 'Show Font Names in English' is disabled in Preferences > Type.
CJK fonts, such as this one, allow to break one character per word, and this extends to Cyrillic glyphs these might have, even with the correct language is picked in Character panel.
The team is considering to treat Cyrillic like non-CJK when the CJK font's Cyrillic is not full-width, but currently sees it as a narrow case.
