@mjauvin thoughts on the apostrophe suggestion in this PR?

@mjauvin thoughts on the apostrophe suggestion in this PR?

@damsfx I don't really like this, we use standard single quote everywhere else, you just need to use double quotes around the whole string.

I also believe that some OS's (or some fonts that those OS's use) may also substitute single quotes with more "fancy" versions as needed. It's likely that won't happen if you are already using a "fancy" quote.

In French, we make the difference between apostrophe ( ’ ) and prime ( ' ) symbols.

• The prime symbol is used it in mathematics and measurements ( e.g. 6'7'' ).
• The apostrophe is a typographical sign for grammatical connections (e.g. Marc’s computer ).

Having said that, I don't have problem following the WinterCMS convention on this subject, I just wanted to standardize the translations because both forms are used in the same file.
My choice was based on habit.

@damsfx I would prefer if you don't escape the single quote and use double quote around the whole strings when a single quote is used inside

[mjauvin]

Unless the other maintainers prefer the escaped single quote?

I prefer single quotes with escapes as it prevents you accidently parsing a var when you are intending to display a variable name. I.e.

echo 'Hello, I\'m sure you meant to set $example';
// vs.
echo "Hello, I'm sure you meant to set $example";

I'm not massively concerned either way though :)

[LukeTowers]

I don't have an opinion personally, although I'd prefer to more closely follow the style conventions of the language in question so that it's a more natural experience for users of that language. Having said that, I don't actually use French so I'll defer to the people who actually use it to provide recommendations on what we use for punctuation in our localization strings.

[bennothommo]

I prefer single quotes and escaping too. Not only does it more evidently separate the actual string from variables and the like, I still have this unproven crackpot theory that favouring these types of strings provides a really marginal performance improvement because PHP doesn't have to parse the strings for variables.

EDIT: Also, happy to take @damsfx's advice on the quotes with respect to using the special quotes depending on the context.

[mjauvin]

Allright, we're going to use single quotes and escape the single quote when present. We should do this accross the code base for consistency.

Thanks @damsfx

@mjauvin Could you add that to the Developer Guide so that we have a published reference for the future?
