Issue 34537: test_gdb fails with LC_ALL=C (original) (raw)

On Python 3.7 and master, test_strings() of test_gdb fails if gdb uses Python 3.6 (before UTF-8 Mode and C locale coercion):

• gdb uses ASCII encoding for stdout
• tested Python uses UTF-8 thanks to the UTF-8 Mode and/or C locale coercion
