Subject: Fix non-ASCII description truncation

Annotated descriptions with non-ASCII characters get truncated, as
outlined in #820108. This happens because extractLine() keeps track of
the line length in terms of displayed characters while using text.substr to
extract lines, failing to account for multi-byte characters (which only
increment line_length by 1).

Fix this by relying on the cursor set by utf8_next_char, rather than
line_length.

Closes: #820108
