What does someone need to be able "to navigate the Internet in their own language"? At the Coalition on Digital Impact (CODI) this year, we looked at the whole "stack" of systems people use, and created our "Language Infrastructure Framework" as a tool to help:

Comments and feedback are definitely welcome!
@danyork Please do not forget that there are many Internet uses in which non-ASCII support is not merely costly in terms of storage but also opens the door to coding errors.
One such use is tiny embedded systems - often sensors and some form of sensor/alarm enunciator/controller-actuator - these can be life critical (hence the need to avoid potential coding errors to support never-used languages) and often need to be in places where power or heat issues mitigate strongly for minimal storage and processing power.
That kind of use lives in an ASCII world. For such devices multi-language support is, at best, an unnecessary burden.
