That is true, but I guess the tradeoff is you would need to recreate the
converters more times.
pragma converts are stackable so it's possible to do the following
```
pragma convert ("IBM-1047")
<strings that need to be encoded in IBM-1047>
pragma convert("UTF-8")
<strings that need to be encoded in UTF-8>
pragma convert(pop)
<strings that need to be encoded in IBM-1047>
pragma convert(pop)
```
