Introduction para. #5

replace "much" with "greatly".

2.4 a)	Replace "(or more)" with "(or more but not all)".

4.18	A diagram showing the structure of the coding space rather than coding of individual characters, and normally showing at least one plane

4.21	Replace the ";" with "," and add "(16,777,216)" before "characters"

4.23	The process where two or more systems, each employing different coded character sets can meaningfully exchange coded character data (retain the graphic symbols and control functions); conversions between the different codes may be involved.

4.24	The set of graphics characters coded in a row of the code table of a plane; cells 032 to 095 form the left half row, and cells 160 to 255 form the right half row.

4.27	add "(65,536)" before "characters".

4.30	Within this coded character set, the planes reserved for private encoding and whose contents shall be undefined in this standard.

4.31	Within this coded character set, those areas within a plane reserved for private encoding and whose contents shall be undefined in this standard.

4.32	The rows and cells allocated for graphic characters in one of the four major subdivisions within the code table of a plane.

4.33	A subdivision of a plane that contains 256 cells from cell 000 to 255.

4.36	Remove the word "function".

Add a definition for the word "SMALL" as used in "LATIN SMALL LETTER A" to indicate the meaning is the "lower-case" of a letter. Our members were concerned that "SMALL" may be misunderstood to mean a "small capital" font rather than "lower case".

5	Para. #3 replace "defining" with "and they define"

Para. #7 replace "The subsequent 158 planes" with "Planes 033 through 095, and planes 160 through 223".

Para. #9 change "last 32 planes" to "last 32 planes (planes 224 to 255)"

change "the characters in them not being" to "and the characters in them shall not be"

6.1	Para. #2 The last sentence is hard to read.

17.	Para. #3 replace "do not comprise a fixed number of bits"

with "comprise a variable, rather than fixed, number of octets".

18.2.2	last para. Clause 13 appears incorrect.

21	Last para. identify page on which Fig. 3 is located.

44	Add a paragraph describing the hex and decimal notation in the code tables for the half rows:

In the tables for the half rows, the decimal value of the cell-octet is located immediately below the character. For hexadecimal (hex) notation for the cells, the half-row tables display the most significant hex digit to the left, and the least significant digit on the top.

Annex A	Identify character subset 150 as "BASIC ALPHABETS OF THE BASE MULTILINGUAL PLANE".
