Tests are not run if the name contains Cyrillic(or Korean) characters . When running flutter tests in IntelliJ IDEA.

When running Flutter tests in IntelliJ IDEA, test descriptions written in Russian are improperly encoded, causing them to appear as escaped Unicode sequences (e.g., \u0422\u0435\u0441\u0442) in the Run/Debug configurations and test output. And test not start.

I have same issue. I wrote test method's name in Korean.
More details about the issue is here.

I created a hacky solution to handle Unicode in Flutter test names, tested with Russian test names only. This works on Linux/Mac. A similar approach can be adapted for Windows.

Steps:

1. Go to your Flutter folder (e.g., /path/to/flutter/bin) and locate the flutter and flutter.bat files.
2. Rename flutter to flutter_orig.
3. Create a new file named flutter with the content below and make it executable using chmod +x flutter.

This script parses Unicode escape sequences and correctly runs tests.

#!/bin/bash

# Decode arguments using Python to handle Unicode escape sequences
decoded_args=()
for arg in "$@"; do
    decoded_arg=$(python3 -c "import sys; print(sys.argv[1].encode().decode('unicode_escape'))" "$arg" 2>/dev/null || echo "$arg")
    decoded_args+=("$decoded_arg")
done

# Form the command with stdbuf for line-buffered output
command=(stdbuf -oL "$(dirname "$0")/flutter_orig" "${decoded_args[@]}")

# Print the command for debugging
echo "Executing: ${command[*]}" >&2

# Execute the command
"${command[@]}"
exit $?

At least some movement on this topic. With each update, I hope that this will be fixed, as I encounter this every day.

Steps:

1. Go to your Flutter folder (e.g., `/path/to/flutter/bin`) and locate the `flutter` and `flutter.bat` files.

2. Rename `flutter` to `flutter_orig`.

3. Create a new file named `flutter` with the content below and make it executable using `chmod +x flutter`.

This script parses Unicode escape sequences and correctly runs tests.

#!/bin/bash

Decode arguments using Python to handle Unicode escape sequences

decoded_args=()
for arg in "$@"; do
decoded_arg=$(python3 -c "import sys; print(sys.argv[1].encode().decode('unicode_escape'))" "$arg" 2>/dev/null || echo "$arg")
decoded_args+=("$decoded_arg")
done

Form the command with stdbuf for line-buffered output

command=(stdbuf -oL "$(dirname "$0")/flutter_orig" "${decoded_args[@]}")

Print the command for debugging

echo "Executing: ${command[*]}" >&2

Execute the command

"${command[@]}"
exit $?

I checked on linux. Works.
