# Table Formats
|
||
|
|
|
||
|
|
Each character map table starts with a single nonzero byte, indicating the table's format.
|
||
|
|
|
||
|
|
## Extended ASCII
|
||
|
|
|
||
|
|
Format 1 is for "extended ASCII". Encoded values 0-127 are identical to ASCII, and encoded values 128-255 are mapped to single Unicode characters.
|
||
|
|
|
||
|
|
The table contains 128 entries, for encoded values 128-255, with the following format:
|
||
|
|
|
||
|
|
u8 Length of Unicode character
|
||
|
|
u8[] Unicode character, UTF-8
|
||
|
|
u8 Length of normalized Unicode character, may be zero
|
||
|
|
u8[] Unicode character in NFD normal form, UTF-8
|
||
|
|
|
||
|
|
The second copy of the character is only present if the character decomposes into multiple characters.
