No. You are looking at the problem from a programmer perspective, but when 
these errors are introduced, there is no programmer present. As a matter of 
fact, the programmers may already have been fired. The person who is 
translating the text is introducing the errors, and he is the one who needs 
to be able to see them and fix them. The best way to do that is for the 
translate/format functions to return a string from which one can deduce that 
a syntax error has occurred, so that the translator (or the user) can see 
the error appearing instead of the properly translated text - without this 
interfering with the user's ability to continue using the software as would 
happen if an exception aborted the entire, potentially time consuming, 
operation. This does not "silently ignore" the errors, it reports them in an 
appropriate way, to the appropriate person.

Now, you could make the case that you, as a programmer, should still have 
the error reported to you by the library so that you can log it (if the 
library doesn't have built-in logging support), which of course would also 
allow you to promptly proceed to ignore everything that's been said and make 
the error handlers throw exceptions. :-)
