Use functions that do not depend on the current locale.
X.509 functions and the like should not vary their behaviour based on
the configured locale, but tolower(3), strcasecmp(3) and strncasecmp(3)
change behaviour based on that.
For example, with tr_TR.utf8, 'I' is not the upper-case version of 'i'.
