Alternative Unicode mappings

There may be several different Unicode characters which look similar to, or provide a similar function to, an APLX character. In order to maximise the probability of being able to represent the text when converting from Unicode to internal representation, APLX accepts as input a number of alternative Unicode values for certain characters. These are as follows:
