[mkgmap-dev] upper and lower case

Mon Jul 24 11:55:26 BST 2017

Hi, I wonder are there functions to convert values to upper or lower cases?
I can't find anything in the style manual. I'm doing a lot of comparison of
name fields such as name~'[Aa]irport' and think it would be much more
efficient to first copy the name to an upper or lower case version and then
do equality matches instead of the regular expression matches (this would
also detect any oddly capitalized names such as AIrport). Any suggestions?

Thanks,
Mike
