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