Is it right to encode "+" and "-" in that way?

I am trying to encode string with UTF-8 format and all required characters instead of "+" and "-" are not formatted.

I investigated NSCharacterSet, and found out that standard URLHostAllowedCharacterSet method is not fully covering my issue.

I decide to create own NSCharacterSet with symbols that should be replaced:

 NSCharacterSet *customCharacterSet = [[NSCharacterSet characterSetWithCharactersInString:@" \"#%/:<>?@[\\]^`{|}+-"] invertedSet];

This is working, but I am interested if it is right to do this replacement by my own, or maybe there is some standard methods that are doing this replacements that I do not find?

If you explicitly need to encode also the valid characters + and - then your custom character set is the right solution.
