Translations

[micheus]

burgom, about to flooding this thread by now I think you questions still are general and can stay here.
But. if you want we can move this post to a dedicated thread for Spanish translation. It's up to you (just let me know and I move this post to it).

1_ you files for reference must be always the English version. Any other file would be needing update - that sounds to be the case. Unfortunately the translators are also volunteers and we don't get these files update frequently.

2_ in a sentence like this {1,". Position <~s ~s ~s>"}, the first field (the number) means an ID and the quoted text is what will be displayed. It can be pure text or contain elements used to be replaced by parameters hard coded. In this case it's a format string and you can understand if checking this documentation.

What is important is that "~?" is used for the formatting process, so you must keep it as it is. Others formatting elements like "\?" must also be kept as they are.

In your question, the use of "[", "<" or its absence were translators choice. Again, your .lang file for reference (template) must always be the English one.
Put the focus on the plain text and leave the special characters/signs as they are and you probably will not get problems.

Also, be sure to save the files using Unicode characters. Your text editor must support this, of course.

Is it clear what I said here? (English isn't my first language, so sometimes I cannot express things correctly).
