1542 Test section lookup by translated message

  1543 

  1544 str.lower() instead of encoding.lower(str) on translated message might

  1545 make message meaningless, because some encoding uses 0x41(A) - 0x5a(Z)

  1546 as the second or later byte of multi-byte character.

  1547 

  1548 For example, "\x8bL\x98^" (translation of "record" in ja_JP.cp932)

  1549 contains 0x4c (L). str.lower() replaces 0x4c(L) by 0x6c(l) and this

  1550 replacement makes message meaningless.

  1551 

  1552 This tests that section lookup by translated string isn't broken by

  1553 such str.lower().
