No, Jacob, the letter 'é' is not 130.
The numeric value assigned to a letter (technically, the codepoint that a
glyph occupies) varies from characterset to characterset. The letter
(glyph) 'é' is not guaranteed have the numeric value (occupy the
codepoint) 130 in /every/ characterset; in some charactersets, that glyph
does not exist at all, while in others, it will occupy a different
codepoint.
For instance,
the character doesn't exist at all in ASCII
in the CP-HU characterset, that character is 0x82
in the UTF16 characterset, that character is 0x00E9
in the CSA_T500-1983 characterset, that character is a two-character
sequence 0xC2 0x65
in the EBCDIC-CP-FR characterset, that character is 0xC0

41 charactersets encode the e-acute glyph as codepoint 0x82
22 charactersets encode the e-acute glyph as codepoint 0x7B
19 charactersets encode the e-acute glyph as escape sequence 0xC2 0x65
12 charactersets encode the e-acute glyph as codepoint 0xC0

1 characterset encodes the e-acute glyph as codepoint 0x60
Note that these values are expressed in a signless hexadecimal format.
Codepoints (when used in characterset documentation) are always positive
values, but /platforms/ often do not support positive values for the entire
range of codepoints that a characterset may contain.
We are discussing the difference between /encoding/ (which, for codepoints
is always signless) and /interpretation/ (which may be signed, as the
interpreter wishes).
