Are all character encoding compatible with ascii, for at least a-z

Some charset don't have all the 128 first identical to ascii, but is A to Z and a to z, always in the sam position?

I had a plan to set apaches default charset to somting odd in my test envirement, for easy detecting sites that don't tell the browser what encoding it sending. But so far, I can't find one that makes A to Z show up as someting else.

There is an other question close to the subject, but thats about all 128 ascii chars:
Are ASCII characters always encoded the same way in all character encodings?

In short: no. The encoding mentioned in the other answer, EBCDIC, has a very different layout, to pick just one example.

Most encodings you find in the wild on the web today are probably ASCII compatible. But there are encodings other than ASCII which are entirely incompatible too.

No, EBCDIC from IBM is the famous exception.

Another testcase is UTF-16 Big Endian, which puts "A" at U+0041. ASCII would treat the first 00 as a NUL, which often is interpreted as an end-of-string.
