I'm not aware of any built-in method to do this, and I suspect it will
depend greatly on how exactly you're trying to render the string to the
display device.  For instance font selection and point size are probably
the biggest factors that determine the rendered representation of a
string, and those are generally variable.  The tools available to you to
figure out the string size in pixels almost certainly varies depending
on the library or framework you're using to handle the actual work.

So, first of all, how do you plan to render your strings, disregarding
the overall length in pixels?  Are you going to have them inserted into
a web page that is viewed by a browser, or are you using something like
GTK, QT, etc. as a conventional graphical user interface, or are you
doing something else?

Can you provide an example of truncating strings the way you need in
another language?
