Do what has been done in various computer software for years - only allow
variable or objects names to use a restricted character set. I am used to
seeing such restrictions as
- first character must not be a number
- can only use characters A-Z, 0-9 and '_' (underscore)
If it is necessary to use UTF-8 characters then only allow those which are
the same in upper and lower case. Problem solved.
