Global replacements

[jancama2]

Say we have a translation in a sheet with interpolated values. We use the same sheet for web and mobile apps and it quite a lot of times ends up with having two rows with the same translation but different interpolation:

• mobile - Máte nové zprávy v%sinboxu.
• web - Máte nové zprávy v{nbsp}inboxu.

We could unify it if a sheet loading tool for each platform would replace some placeholder with platform specific strings. Something like:
Máte nové zprávy v inboxu.

Which would be be replaced based on a configuration for web in the lokse config

{
   replacements: { ' ': '{nbsp}' }
}

to: Máte nové zprávy v{nbsp}inboxu. which we can than use for react-intl interpolations.

Pros:

• we can let a person translating the sheet to use commonly known things like   even though we can't use them straigt away in react-intl
• we can have only one translation in the sheet for each message id and not two or more based on the platform needs
