Acronyms in Titles

[shranac]

my file names are all lower case such as autocomplete.html, which when rendered is Autocomplete, which is great. But when I have an acronym in the title I would like it to be all caps. I could name the file x-y-z.html But that comes out as X Y Z instead of XYZ. How do I make the title come out so that acronyms are formatted properly?
