To Convert to or from an internal name in sharepoint
Sharepoint internal names can only include letters/numbers and underscores.
Any other character needs to be encoded using this scheem:
Convert the character's ascii representation to a four digit hex number, prefixed with 'x' and surrounded by underscores.

I don't know how a literal "_x" is encoded, but no doubt there is a convention, such as encoding literal _x as _xx (thus a _x(x)+ decodes to _($1) )(But this is just speculation.)
