This is not a question about software or tools. Please don't comment if you think that's what I'm asking about.
Parsing Unicode-encoded text is a major pain for a software developer, so I thought there must be a better way and quickly came up with an extensible way to do it without too much overhead (no analysis done yet). The scheme depends on no script having more than 127 characters -- without distinction between upper and lower case characters or any special graphical representation of the same basic character (i.e. all of the different ways to write a character based on context, counts as one character).
So, are there any scripts which have more than 127 characters?
