LSCEF

LSCEF (Lebster's Standard Character Encoding Format) is a method of storing character data created by User:Lebster. Its purpose was to provide an alternative to ASCII for EsoLang creators.

Usage in interpreters

Javascript:

const toLSCEF=(c=>"\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t".indexOf(c))
const fromLSCEF=(c=>"\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t"[c])

toLSCEF("<") // Returns 93
fromLSCEF(93) // Returns "<"

Python:

toLSCEF=lambda c:"\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t".find(c)
fromLSCEF=lambda c:"\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t"[c]

toLSCEF("A") # Returns 2
fromLSCEF(2) # Returns 'A'

SWI-Prolog:

lscef(C, N) :- nth0(N, Chars, C), string_chars("\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t", Chars).

Query:
lscef(X, 12).
lscef('\t', Y).
% results in X = 'K', Y = 97

Chez Scheme:

(define (toLSCEF n) (string-ref "\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t" n))
(define (index v l) (cdr (assq v (map cons l (enumerate l)))))
(define (fromLSCEF c) (index c (string->list "\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t")))

(pretty-print (toLSCEF 0)) ; Returns \#newline
(pretty-print (fromLSCEF #\h)) ; Returns 35

Wikipedia:C (programming language):

#define LSCEF_STR "\n ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!\"£$%^&*(){}[]-=_+;'#~@:,./?><\\|`\t"
#define LSCEF_STR_LEN 98

int toLSCEF(char c);
char fromLSCEF(int n);

int toLSCEF(char c)
{
  int i;
  for(i = 0; i < LSCEF_STR_LEN; ++i)
    if(c == LSCEF_STR[i])
      return i;
  return -1;
}

char fromLSCEF(int n)
{
  if(n < LSCEF_STR_LEN)
    return LSCEF_STR[n];
  else
    return (char)-1;
}
