They don't exist. FPC has been designed to either use the system
encoding
(which can be utf8). In this case, the string routines from sysutils do
what you want. The other option is to use widestrings;
length(utf8decode(s)) will return the length of an utf-8 string.
Sorry, I'm very new to Unicode support. Wouldn't it be useful to have
UTF-8 and UTF-16 (and all the other encodings) functions in FPC?
It's not that easy, for example upper/lower casing, comparing etc. of
unicode requires usually external big tables which we don't want to pull
into fpc.
I agree. Though smartly build Unicode table is not such big (it may increase
executable size by ~80KB), but it is absolutely not necessary. All
contemporary platforms have sufficient Unicode services. It is easy to
employ them.
