This file describes the custom character encoding that the non-Unicode
versions of the Chortle font use.

The reason for this custom encoding is so that this font can be used
on older computers and software that doesn't have Unicode support.  For
example, there is a bug in Xterm that causes my X server to crash once
every day or two; the workaround is to use rxvt instead, which, alas,
doesn't support Unicode.

This encoding is compatible with ISO 8859-1, but with 21 symbols in the
8859-1 punctuation area (160-191) changed to IPA symbols that I use in my
English classes, and seven symbols that Microsoft Word needs added in the
unused area between ASCII and 8859-1 (145-151).

Here is an ASCII description of all of the differences between ISO 8859-1
and the encoding used by the non-Unicode versions of the Chortle fonts.
This description is also a visual chart in the file ENCODING.png

Decimal	Hex Octal Chortle symbol		8859-1 symbol
145	91  221   Opening single quote		Unused
146     92  222   Closing single quote		Unused
147	93  223   Opening double quote		Unused
148	94  224	  Closing double quote		Unused
149	95  225   Bullet			Unused
150     96  226   Endash (--)                   Unused
151 	97  227   Emdash (---)                  Unused
157     9d  235   Arrow pointing right (-->)    Unused
162     a2  242   Upside down "c"		Cent symbol
163	a3  243   Upside down "r"		Pound currency symbol
164 	a4  244   "ah" vowel sound		Currency symbol
165     a5  245   Epsilon symbol		Yen currency symbol
166     a6  246   Upside down omega		Broken pipe symbol
167     a8  250   Upside down "e"               Umlaut / Dieresis
172     ac  254   "Eng" letter ("ng" sound)     Logical not
173	ad  255   Theta				Soft hyphen
175	af  257   Integral sign			Marcon
176	b0  260   "t" + Integral sign		Degree sign
177     b1  261   Looks like a lowered "3"      +/- symbol
178     b2  262   "d" + "3"-like symbol         Superscripted "2"
179     b3  263   Upside down "v"               Superscripted "3"
180     b4  264   Upsize down "w"               Acute accent
181     b5  265   Modified "eng" ("ny" sound)   Mu 
182     b6  266   Upside down "e" with curly    Paragraph symbol
183     b7  267   Large bullet symbol		Middle dot
184     b8  270   Backwards epsilon with curly  Cedilla
185     b9  271   "?" w/o dot (glottal stop)    Superscripted "1"
188     bc  274   Upside down "r" w/ line below 1/4 symbol
190     be  276   "l" with line below           3/4 symbol 

With two exceptions, all of the above symbols have corresponding Unicode
code points.  The two symbols that would need to be placed in the
private use area of Unicode are the upside down "r" and "l" with lines
below them.  The reason these symbols are not in Unicode is because 
"r" + line below would be represented by 0x279 and the combining mark
0x329, and "l" + line below would be represented by "l" and the same 
combining mark.  Unfortunatly, the software that runs on my older
computer does not support combining marks, so I have had to create
custom non-Unicode characters.
