Current behavior

When using nestjs/swagger with this minimal example in a folder containing a non-ASCII character, I get errors "Cannot find module":

node:internal/modules/cjs/loader:1413
  throw err;
  ^

Error: Cannot find module '/mnt/Data/testnéstcli/testcli/src/dto/test.dto'
Require stack:

    '/mnt/Data/testnéstcli/testcli/dist/app.module.js',
    '/mnt/Data/testnéstcli/testcli/dist/main.js'
  ]
}

When digging to understand the error, it comes from the generated app.controller.js:

exports.AppController = AppController;
__decorate([
    (0, swagger_1.ApiOperation)({ summary: 'Hello' }),
    (0, swagger_1.ApiResponse)({ status: 200 }),
    (0, common_1.Get)('/hello'),
    openapi.ApiResponse({ status: 200, type: [require("/mnt/Data/testnéstcli/testcli/src/dto/test.dto").TestDto] }),
    __metadata("design:type", Function),
    __metadata("design:paramtypes", []),
    __metadata("design:returntype", Promise)
], AppController.prototype, "getHello", null);

Note that the error is also in the generated test.dto.js, regarding the enum type (removing this enum property still yields the other error):

const test_entity_1 = require("../entities/test.entity");
class TestDto {
    id;
    name;
    enum;
    static _OPENAPI_METADATA_FACTORY() {
        return { id: { required: true, type: () => Number }, name: { required: true, type: () => String }, 
enum: { required: true, enum: require("/mnt/Data/testnéstcli/testcli/src/entities/test.entity").TestEnum } };
    }
}

The issue is solved as soon as I remove the swagger plugin from nest-cli.json (which removes the _OPENAPI_METADATA_FACTORY, and lets the field type of AppController be defined by the @ApiResponse).

It is also solved if I rename "testnéstcli" to "testnestcli"

Install it in a folder with non-ASCII character, e.g. "tést".

Steps to reproduce

No response

Expected behavior

The generated paths should be relative, and point to the generated version instead of the typescript source: ../entities/test.entity instead of /mnt/Data/testnéstcli/testcli/src/entities/test.entity

Probably related to #3162, but more general?
It seems not to happen on Windows, as I had the original issue on a more comprehensive repo made by someone working on Windows.
