keyword
The keyword must be at least one character and less than 80 characters long.Keywords are always interpreted according to the ISO/IEC 8859-1 (Latin-1) character set [ISO/IEC-8859-1].
They must contain only printable Latin-1 characters and spaces; that is, only character codes 32-126 and 161-255 decimal are allowed.
To reduce the chances for human misreading of a keyword, leading and trailing spaces are forbidden, as are consecutive spaces.
Note also that the non-breaking space (code 160) is not permitted in keywords, since it is visually indistinguishable from an ordinary space.

text
The tExt chunk is interpreted according to the ISO/IEC 8859-1 (Latin-1) character set [ISO/IEC-8859-1]. The text string can contain any Latin-1 character. Newlines in the text string should be represented by a single line feed character (decimal 10); use of other control characters in the text is discouraged.The zTXt chunk contains textual data, just as tEXt does; however, zTXt takes advantage of compression. The zTXt and tEXt chunks are semantically equivalent, but zTXt is recommended for storing large blocks of text. A zTXt chunk contains: Keyword: 1-79 bytes (character string) Null separator: 1 byte Compression method: 1 byte Compressed text: n bytes
iTXt International textual data This chunk is semantically equivalent to the tEXt and zTXt chunks, but the textual data is in the UTF-8 encoding of the Unicode character set instead of Latin-1. This chunk contains: Keyword: 1-79 bytes (character string) Null separator: 1 byte Compression flag: 1 byte Compression method: 1 byte Language tag: 0 or more bytes (character string) Null separator: 1 byte Translated keyword: 0 or more bytes Null separator: 1 byte Text: 0 or more bytes
