I noticed some text (from exotic sets of characters) displays only as lines.
It happens over a lot of sites and looks not related to foreign languages (I can see Korean, Cyrilic, Kanji, etc. correctly) but to some mix of graphic play. Safari displays the text correctly as it is supposed to be, so is not a lack of system fonts.
Shields on/off don’t change the display.
