Replace invisible CR with character class Icon[^!-~]

The literal CR character is frequently corrupted by:
- Text editors auto-trimming invisible chars
- Formatting tools (editorconfig) normalizing line endings
- Copy/paste operations losing special characters
- IDE auto-formatting and linting tools

Character class pattern is collaboration-safe and functionally identical.
