I'm happy to use all the multibyte string functions in my app, but when using external libraries it would a pain to find and replace them all.
Given I can control external input so that only UTF-8 data will be present, issues that arise from comparing two different encoding types won't be a problem (i.e. str_replace is fine as is).
So which string functions do I need to replace with the mb_* equivalent?
So far I'm sure I need to replace
- strpos()
- strlen()
- substr()
Are there any others?
Alternatively, is using overloading a viable option, or is this likely to cause issues?
