I’ve given up on entering non-ASCII characters when entering data on-line

Posted by jpluimers on 2019/06/17

I live in a street that has a non-ASCII character in it: Pyreneeën.

I’ve reverted back to entering the street name as plain ASCII for a simple reason:

Too often the ë gets mangled into encoding gibberish, similar to the é example in [WayBackWhen Good Characters Go Bad: A Guide to Diagnosing Character Display Problems as these characters are very near both in UTF-8 and in the [WayBackUnicode Characters in the Latin-1 Supplement Block:

I’ve seen these encodings, where only the top encoding right and the degeneration gets worse over time:

# encoded UTF-8 (hex.)
0 ë 0xC3 0xAB
1 ë 0xC3 0x83 0xC2 0xAB
2 ë 0xC3 0x83 0xC2 0x83 0xC3 0x82 0xC2 0xAB
3 ë 0xC3 0x83 0xC2 0x83 0xC3 0x82 0xC2 0x83 0xC3 0x83 0xC2 0x82 0xC3 0x82 0xC2 0xAB
4 ë 0xC3 0x83 0xC2 0x83 0xC3 0x82 0xC2 0x83 0xC3 0x83 0xC2 0x82 0xC3 0x82 0xC2 0x83 0xC3 0x83 0xC2 0x83 0xC3 0x82 0xC2 0x82 0xC3 0x83 0xC2 0x82 0xC3 0x82 0xC2 0xAB
5 ë 0x26 0x65 0x75 0x6d 0x6c 0x3b

The last one seldomly happens, the first one relatively often, just like [Archive.is] fd.nl did a while on their finanancial pages.

These mistakes become sort of understandable (but not forgivable) when you look at the below table-fragment (the full table is at[WayBack] Unicode/UTF-8-character table – starting from code position 0080).

The sad thing: even with ASCII characters, system goof up systems; an apostrophe can be enough:

[WayBack] … My old card did have my last name (Ts’o) correct. The new card… – Theodore Ts’o – Google+

Via [WayBackUnicode on Credit Card Names is unthinkable, but currently even ASCII is too hard…. – Kristian Köhntopp – Google+

Even sadder: the “Via” post got goofed up by the WayBack machine from the internet archive: Source: Encoding horror: Wayback Machine “Sorry.This snapshot cannot be displayed due to an internal error.”.

My conclusion is that despite all the fuzz about AI, we’re never going to reach singularity as way too many things keep being broken all the time.

Conversion table

Note I used [WayBackUTF-8 encoder/decoder in addition to the below table to create the above degeneration sequence. It is on Source: mothereff.in/utf-8 at master · mathiasbynens/mothereff.in
