| /* When GCC reads UTF-8-encoded input into its internal UTF-8 |
| representation, it does not apply any transformation to the data, and |
| in particular it makes no attempt to verify that the encoding is valid |
| UTF-8. Historically, if any non-ASCII characters were found outside a |
| string or comment, they were treated as stray tokens and did not |
| necessarily produce an error, e.g. if, as in this test, they disappear |
| in the preprocessor. Now that UTF-8 is also supported in identifiers, |
| the basic structure of this process has not changed; GCC just treats |
| invalid UTF-8 as a stray token. This test verifies that the historical |
| behavior is unchanged. In the future, if GCC were changed, say, to |
| validate the UTF-8 on input, then this test would no longer be |
| appropriate. */ |
