fix: #1405 - added unbreakable spaces to welcome message

[monsieurtanuki]

Impacted files:

• app_en.arb
• app_fr.arb

What

• Added unbreakable spaces to welcome message, so that "Open Food Facts" will be on the same line
• The fix is only for English and French, and only for the welcome message
• It may be a good idea to extend that fix to other languages and to other messages
• In that case, perhaps we'd be better off
  • removing the unbreakable spaces from the translated strings
  • systematically replacing 'Open Food Facts' with 'Open\u00A0Food\u00A0Facts'

Fixes bug(s)

• Can we ensure Open Food Facts is never cut into 2 parts (carriage return before Open) ? #1405

@abhay1821 That's what I meant.
Additional thought: it's a bit tricky to use \u00A0 because if you copy/paste it, it becomes the character unbreakable space (at least on my mac book):

... becoming ...

Which is still correct, but not so simple to detect for instance when reading the code or code differences via github (where an unbreakable space looks like a space).

Hi @monsieurtanuki Thank you Really appreciate your input on this. So when I tried something like this I got caught with an Exception. :(

@abhay1821 I guess it's just that the escape formats are different in dart and in .arb files.

@monsieurtanuki So I have one more doubt, So when I tried with small width devices It looked something like this.

Small Device Width

@abhay1821 That's another story/issue/PR: the font size is not adapted to the screen size. Perhaps using FittedBox would do the trick. But it was not the point of the current issue: feel free to create a new issue.

Thank you for your guidance. I would do It when this PR would get merged.
