This function would examine the current locale and, if it's a problematic one, convert the string to lower case on its own (calling zend_tolower on non-problematic characters). Alternatively, zend_normalize_class_name could switch LC_CTYPE to an appropriate locale (e.g. "UTF-8"; the locale could be determined at compile time), call zend_str_tolower_copy, then switch back before returning. Then, any appropriate function (e.g. zend_resolve_class_name, zend_lookup_class_ex, class_exists, class_alias) would call zend_normalize_class_name instead of zend_str_tolower_copy/ zend_str_tolower_dup. The two problems with this approach are 1) additional time-cost. However, if done right, this should have little impact. 2) break class names using words in the locale-language. For example, a class named "IzgaraGörünümü" would be converted to "izgaragörünümü", rather than "ızgaragörünümü". However, this impact should be less than that caused by the current bug. Does this bug pop-up for locales other than Turkish, Azerbaijani and Kurdish ?
