By removing unnecessary ;s and do some tricks, you can make this even shorter.function a(c){b='',d=c.split('\n');for(e=0;d[0][e++];){for(i=f=0;g=d[i++];){h=g[e-1];if(h=='o')b+=(b?' ':'')+String.fromCharCode((d.length+4-i)%7+65);if(h=='|')f=f||4;f*=1+(g[e]=='\\');}if(f)b+='/'+f}return b} (209 chars)
