HEX and Unicode

I just noticed the many similarities betwee hexadecimal and unicode (basic latin). I have made a list:

Text - Hex - Unicode
a - 61 - 0061
b - 62 - 0062
c - 63 - 0063
d - 64 - 0064
e - 65 - 0065
f - 66 - 0066
g - 67 - 0067
h - 68 - 0068
i - 69 - 0069
j - 6A - 006A
k - 6B - 006B
l - 6C - 006C
m - 6D - 006D
n - 6E - 006E
o - 6F - 006F
p - 70 - 0070
q - 71 - 0071
r - 72 - 0072
s - 73 - 0073
t - 74 - 0074
u - 75 - 0075
v - 76 - 0076
w - 77 - 0077
x - 78 - 0078
y - 79 - 0079
z - 7A - 007A

0 - 30 - 0030
1 - 31 - 0031
2 - 32 - 0032
3 - 33 - 0033
4 - 34 - 0034
5 - 35 - 0035
6 - 36 - 0036
7 - 37 - 0037
8 - 38 - 0038
9 - 39 - 0039

In order to find the right unicode characters I use a nice little tool of Gaijin.at, text2grep. With this tool I can convert texts to hex codes. I just have to add two zeros in front of each hex code and I know directly which unicode to use.
