Error: invalid integer contant at line 445

[grince]

I just downloaded that wonderful bash-script for this wonderful idea.

I am running Debian 12, installed jq and jq2a additionally.
but when I try to start the script without any parameter (so, a random oil painting should be shown), I receive the following:

$./aic.sh
./aic.sh: line 445: 16#: invalid integer constant (error token is "16#")
Bacchic Revels, c. 1740
Johann Georg Platzer (Austrian, 1704–1761)

this happens also a second time:
$./aic.sh
./aic.sh: line 445: 16#: invalid integer constant (error token is "16#")
Queen Philippa at the Battle of Neville's Cross, c. 1789

Hey, I also wanted to test this and ran against this issue.

It looks like there are a couple issues, one is that sometimes the row consists of <pre, which produces this particular error.

Once we get past that, the regex is not prepared to handle  , so it passes a lot of <span style=...>&nbsp;</span> down the road producing the same issue inconsistently.

Here is a quick patch I prepared to play with things :-)
Note that I replace   with "U+202F   NARROW NO-BREAK SPACE".
