_collect_tt_t1_character_widths casts the /Widths entry of a TrueType or Type1
font to an ArrayObject and enumerates it:

widths_array = cast(ArrayObject, pdf_font_dict["/Widths"])
for idx, width in enumerate(widths_array):
    current_widths[chr(idx + first_char)] = int(width)

The cast has no effect at runtime, so a file storing a string there is iterated
character by character and raises 'ValueError: invalid literal for int() with
base 10' out of extract_text().

The entry is now checked and a font whose widths cannot be read is reported and
skipped, which is how the loop below already handles a non-numeric width entry.

Offline suite passes, 1390 tests.

Used Claude (Opus) to help locate and patch this; I reviewed and tested the change.
