Guys, this happened to me in the browser and basically there is an option in the "Site data on the device" that by default "Delete data that sites have saved on the device when you close all windows" just look in the settings and check the option "Allow sites save data on the device"
@smajira The website is in one of the old 8-bit Windows encodings rather than UTF but someone posted in UTF anyway. Non-ASCII characters (in this case, smart quotes) require several bytes in UTF, but Windows encoding reads each byte as a separate character. (I see this often on Slashdot.)
