So the double arrow is OK in most cases. It is worth checking on other readers (Pocketbook, other Kobo models, Tolino, Onyx etc.)

On my Forma using Charis SIL, the double arrow showed up okay. Testing the Kobo supplied fonts, only AR UDJingxihei, Kobo Tsukushi Mincho and Kobo UD Kakugo supported the double arrow glyph. If I converted the epub3 to kepub, the double arrow worked on any font since the kepub renderer will look for a missing glyph. Other than Courier Dark, my sideloaded fonts all supported the double arrow glyph.
On a Tolino EPOS, the double arrow worked with the default font.
The "=>" pair would likely be the best for catering to the LCD.
