### Godot version

4.0.dev (ba9491f87)

### System information

Windows 11 Chrome 109.0.5414.75 (Official Build), iOS 16.2 Safari

### Issue description

When exporting a simple project for Web with any GDScript like following:
```gdscript
extends Control

```
will print the following error to the console:
```
USER ERROR: U_ILLEGAL_ARGUMENT_ERROR
   at: _is_confusable (modules\text_server_adv\text_server_adv.cpp:6151)
```

For more complex project, following additional errors are showing:
```
USER ERROR: U_FILE_ACCESS_ERROR
   at: _spoof_check (modules\text_server_adv\text_server_adv.cpp:6174)
USER ERROR: U_ILLEGAL_ARGUMENT_ERROR
   at: _is_confusable (modules\text_server_adv\text_server_adv.cpp:6151)
```
When I've inserted `print_line(p_string)` at text_server_adv.cpp line 6172, following logs are collected:

It seems that the identifiers of *.gd files are printed to the console.


### Steps to reproduce

1. Open minimal reproduction project.
2. Exports to Web.
3. Open exported site with Chrome and open developer console.
4. Following error logs will be seen (reproduced): `USER ERROR: U_ILLEGAL_ARGUMENT_ERROR`
