I hope this bug can be fixed since it is quite simple:

[bug #5254] "cvtenc -EscapeIn yes" use wront encoding
Submitted By: yjchen    group: GNUstep

Shouldn't the patch rather be this (assuming if you want to escape the input it must be in Unicode format [ is that correct?]):

 It doesn't work because in your patch,
 the iEnc is set to NSUnicodeStringEncoding for "-EscapeIn Yes" case,
 and this iEnc is immediately used to read the file,
 which is in ASCII (local) encoding or Unicode encoding.
 For the ASCII encoding, it fails.
The input file could be in Unicode encoding or local encoding (ASCII actually).
 That's the reason the if... in your patch is checking.

 So for "-EscapeIn Yes" and input file is in local encoding (ASCII),
it should read the file in iEnc encoding, convert \uXXXX into Unicode in NSString,
 then write this NSString using the iEnc again (line 234-238)
 since the iEnc is the encoding of user environment.

 For "-EscapeIn Yes" and input file is Unicode,
using iEnc is still correct because input and output are all Unicode encoding (iEnc).

 Hope my explanation is clear for you.
