Bug Summary and Steps to Reproduce
example.zip
Bug Summary:
Steps to reproduce:
- Create header file test.h with a struct A and include a comment with the char: ä or ö
* test struct with: ä
*/
struct A
{
int a1;
long a2;
char a3;
bool a4;
};
- Save header file in the encoding ISO 8859-15 ( Set vscode setting: "files.encoding": "iso885915" )
- Create source file test.cpp, save it in encoding "ISO 8859-15", include test.h and use the struct A
#include <test.h>
int main( int argc, char** argv )
{
A a;
a.a1 = 1;
return a.a1;
}
- Close test.h and restart Inteliisense for active file
- The following error appears: "incomplete type "A" is not allowedC/C++(70)"
If test.h is open the error does not appear.
I suspect that the error is some encoding releated problem.
if I change the encoding of the files to UTF-8 the error does not appear.
Expected behavior:
No error should appear.

Confirmed.
I'm assuming that it's loading as a UTF-8 file and byte E4 (which is
äin ISO-8859-15) is an invalid character in UTF-8.Likely related to the changes in the buffer management.

schattenmann80 This was already fixed for our pending 1.23.3 release as part of #13028 (although the current plan is to not release that till January due to vacations).
