On my Mac 10.11.6 using LC 9.0.0 dp4 both of those code snippets
produce '26' in an egalitarian manner.

There should be no reason why:

 put baseConvert(codePointToNum("&"), 10, 16)

should make your computer "all stuffy". If it is then there is a bug to report.

However, "(baseConvert: bad destination base)" does not help much.

This mainly because your example was wrong.

I tried this:

put baseConvert(codePointToNum("&"), 10, 16)  because your syntax was 
the wrong way round,


BUT it go "all stuffy" about the codePointToum, so I did this:

put codePointToNum("&") into NUMM
put baseConvert(NUMM, 10, 16)

and got the number.

How can I get it as a Hex number?


Two options - you can use baseConvert:

  put baseConvert(10, 16, codepointToNum("§")

or you can use format:

  put format("%x", codepointToNum("§"))

The latter is much more flexible e.g.:

  put format("\\u{%06x}", codepointToNum("§"))

Gives the codepoint as the escape sequence for JSON strings (for 
example).
