lottie: fix text update

The occurrence of a 'carriage return' (13) or 'end of text' (3)
caused the skipping of the next character check, immediately
searching for it in the list of available characters.
If the next character was also 13 or 3, it led to incorrect
interpretation; however, if it was the last character in the
sequence, a crash occurred.
