Here's Nahakhontl:
There are lower and upper case letters, but they serve to distinguish word boundaries - all words start with an upper case letter. Sentences are separated by spaces.
This says:
Ôpex dur dér þelsan vé yoh čaþ glôžen doĥ hôga fôl žakír u saônal.

This is an idiom used for admonishing someone who has assumed malicious intent for something gone wrong, when the cause is really incompetence or ignorance.
