Fix Translation not found when contains non-standard character

[N1ebieski]

Partially fixes laravel/vs-code-extension#400

This PR is related to my previous PR #19

Stillat\BladeParser\Document\Document::fromText treats multibyte characters as indentations and spaces resulting in a miscalculated Node position. so my previous PR replaces all multibyte characters with a singlebyte placeholder.

But if a user has any multibyte characters (symbols etc.) inside translations for example: (arrow → is a symbol)

{{ __('Where to find the ID: Log in to the dashboard, go to Products → Settings → Categories, then click Edit next to the selected category. The category ID can be found on the left side at the bottom of the form.') }}

then linkProvider cannot find such an element in the translation repository.

This PR improves my previous PR. Only Node's position is being corrected. The Node's innerContent remains unchanged.
