I have a lot of these for both standard and "symbol" fonts, but only for
characters 0-255. You could omit the standard keyboard characters, however,
and add to the range. The way I created mine was as follows:
1. Create a column with 16 columns and 32 rows.
2. In the odd-numbered columns, enter the numbers 0 to 255 (0-31 in column
1, 32-63 in column 3, and so on).
3. In the even-numbered columns, press Alt+<the corresponding number> to
insert the character. You'll quickly figure out you can omit the first two
columns, since character 0-31 are all control characters; the first "real"
character is 32 (space).
4. Once you have created this table, you can change the font in the
even-numbered columns and get a chart for a different font; this is
especially handy for symbol fonts.
FWIW, I rarely use these charts any more except when I want to see how the
character actually looks in print. Instead, I usually use the Symbol dialog
or a built-in or custom keyboard shortcut; see
