Text workspace
Check whether a text reads the same forwards and backwards under its comparison rules.
Method and limits
Prepare the text according to the rules for spaces, letter case and punctuation, then compare both reading directions. Read the result in relation to that preparation, since changing a rule can change the answer.
NFC normalization keeps accents. Case, whitespace and punctuation have separate switches. Unicode letters, numbers and symbols remain; reversing uses graphemes. Longest means a contiguous part of the normalized text, not of the original spelling.
