   8 // 1. non_camel_case_types
   9
  10 // Can start with non-lowercase letter
  11 struct Θχ;
  12 struct ヒa;
  13
  14 struct χa;
  15 //~^ ERROR type `χa` should have an upper camel case name
  16
  17 // If there's already leading or trailing underscores, they get trimmed before checking.
  18 // This is fine:
  19 struct _ヒb;
  20
  21 // This is not:
  22 struct __χa;
  23 //~^ ERROR type `__χa` should have an upper camel case name
  24
  25 // Besides this, we cannot have two continuous underscores in the middle.
  26
  27 struct 对__否;
  28 //~^ ERROR type `对__否` should have an upper camel case name
  29
  30 struct ヒ__χ;
  31 //~^ ERROR type `ヒ__χ` should have an upper camel case name
  32
  33 // also cannot have lowercase letter next to an underscore.
  34 // so this triggers the lint:
  35
  36 struct Hello_你好;
  37 //~^ ERROR type `Hello_你好` should have an upper camel case name
  38
  39 struct Hello_World;
  40 //~^ ERROR type `Hello_World` should have an upper camel case name
  41
  42 struct 你_ӟ;
  43 //~^ ERROR type `你_ӟ` should have an upper camel case name
  44
  45 // and this is ok:
  46
  47 struct 你_好;
  48
  49 fn main() {}
