… space (pythonGH-156659) XML defines white space as " \t\r\n" (see XML 1.0, 2.3), but str.strip() also strips other characters, such as U+00A0. Such characters could be lost in ElementTree.indent(), in canonicalize(strip_text=True), and when parsing with the whitespace-in-element-content feature turned off.

XML defines white space as " \t\r\n" (see XML 1.0, 2.3), but str.strip()
also strips other characters, such as U+00A0. Such characters could be
lost in ElementTree.indent(), in canonicalize(strip_text=True), and when
parsing with the whitespace-in-element-content feature turned off.
