+===Wordlists (Special Considerations)===
+
+====Japanese====
+1. Users will most likely separate the words with UTF-8 ideographic space.
+(UTF-8 bytes: 0xE38080) When splitting for validation or joining for generation, replace
+all instances of ascii space with the ideographic space, and in case of a mixture of space
+types, also replace just before seed generation.
+
+2. Word-wrapping doesn't work well, so making sure that words only word-wrap at one of the
+ideographic spaces may be a necessary step. As a long word split in two could be mistaken easily
+for two smaller words (This would be a problem with any of the 3 character sets in Japanese)
