There's the problem that "appears" is a visible phenomenon and unicode strings can contain non-visible characters and multiple ways to represent the same visible information. Normalization is supposed to help here, but some sites may fail to do this or do incorrectly, etc.
- josephcsible 2y agoBut the MRZ of a passport doesn't contain any of those problem characters.
- ks2048 2y agoBut on some random website, with people copy-pasting from who-knows-what, they will have to normalize or validate, etc. to deal with such characters.
- josephcsible 2y agoThe point is if the standard were to enter it like in the MRZ, it would be easy to validate.
