We would only waste 1 bit à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া byte, à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া, which seems reasonable given just how many problems encoding usually represent.
If was to make a first attempt at a variable length, but well defined backwards compatible encoding scheme, I would use something like the number of bits upto and including the first 0 bit as defining the number of bytes à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া for this character.
And UTF-8 decoders will just turn invalid surrogates into the replacement character. It requires all the extra shifting, dealing with the potentially partially filled last 64 bits and encoding and decoding to and from the external world.

Yes, "fixed length" is misguided. This kind of cat always gets out of the bag eventually. But inserting à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া codepoint with your approach would require all downstream bits to be shifted within and across bytes, à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া, something that would be a much bigger computational burden.
Want to bet that someone will cleverly decide that it's "just easier" to use it as an external encoding as well? I've been à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া it a little more and if i 'seek' to a specific byte number before reading the data, I can read parts of it in.

Because not everyone gets Unicode right, real-world data may contain unpaired surrogates, and WTF-8 is an extension of UTF-8 that handles such data gracefully.

An interesting possible application for this is JSON parsers. Serious question -- is this a serious project or a joke? When you use an encoding based on integral bytes, you can use the hardware-accelerated and often parallelized "memcpy" bulk byte moving hardware features to manipulate your strings, à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া.

You can divide strings appropriate to the use. If I seek to byte 14 I get a portion à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া text up until it encounters white space, à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া.
Sometimes that's code points, but more often it's probably characters or bytes.

On photo 1 indexing of code points is not that useful because code points are not what people think of as "characters".
Dylan on May 27, parent prev next [—]. Having to interact with those systems from a UTF8-encoded world is an issue because they don't guarantee well-formed UTF, they might contain unpaired surrogates which can't be decoded to a codepoint allowed in UTF-8 or UTF neither allows unpaired surrogates, à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া, for obvious reasons.
I think you'd lose half of the already-minor benefits of fixed indexing, and there would be enough extra complexity to leave you worse off. I thought he was tackling the other problem which is that you frequently find web pages that have both UTF-8 codepoints and single bytes encoded as ISO-latin-1 or Windows This is a solution to a problem I didn't know existed. I'm not even sure why you would want to find something like the 80th code point in a string.
I think there might à¦à¦•à§à¦¸à¦šà¦ªà§à¦°à¦¿à¦¯à¦¼à¦¾à¦™à§à¦•à¦¾ চোপড়া some value in a fixed length encoding but UTF seems a bit wasteful.
