Description

We have a .cpp google test file, with UTF-8 encoded characters in some of our test names, for example:

TEST(stringReplace, Can_find_matching_characters_differing_case_Àà)

When this is executed using the --gtest-output:xml flag, it is generating an .xml file which is declared as having UTF8 encoding (<?xml version=“1.0” encoding=“utf-8”?>), however those UTF8 characters are each being output as single byte ASCII characters.

This is causing issues when attempting to consume these files through an Azure Pipeline, using the PublishTestResults task.

Research direction
Investigate the XML output generation code in googletest, likely in files like googletest/src/gtest filepath.cc or googletest/src/gtest.cc. Look for where test names are written to XML and ensure proper UTF 8 encoding is applied. Check if the issue is in character conversion or the XML declaration. Refer to the issue comments for any additional insights.
