 Try not to burden translators with translating messages that are e.g. slight variations of other messages.
 In the GUI, avoid the use of text where an icon or symbol will do.
-Make sure that placeholder texts in forms don't end up in the list of strings to be translated (use `<string notr="true">`).

 ### Do not translate internal errors
 
-Do not translate internal errors, or log messages, or messages that appear on the RPC interface. If an error is to be shown to the user,
-use a translatable generic message, then log the detailed message to the log. E.g. "A fatal internal error occurred, see debug.log for details".

 This helps troubleshooting; if the error is the same for everyone, the likelihood is increased that it can be found using a search engine.
 
 ### Avoid fragments
 
-Avoid dividing up a message into fragments. Translators see every string separately, so may misunderstand the context if the messages are not self-contained.
