The Television Explorer searches primarily English language news channels, with the notable exceptions of Telemundo and Univision. In some cases, accented characters have not displayed correctly in graph titles under all circumstances and we've updated the Television Explorer today with full Unicode support. Thus, you can now search for "inmigración" on KSTS (Telemundo in San Francisco) and KDTV (Univision in San Francisco) and all graphs will correctly display the accented characters.
