func Decode ¶

func Decode(text string) string

Decode converts Memegen URL format back to user text.

This reverses Encode by processing replacements in the opposite order:

1. Restore tilde-encoded specials and double-quote sequences.
2. Restore underscores (double underscore = literal, single = space).
3. Restore dashes (double dash = literal dash).

func Encode ¶

func Encode(text string) string

Encode converts user text to Memegen URL-safe format.

The replacement order matters:

1. Escape literal underscores (_) and dashes (-) by doubling them.
2. Convert spaces to underscores.
3. Replace remaining special characters with tilde or quote sequences.

func NormalizeQuotes ¶

func NormalizeQuotes(text string) string

NormalizeQuotes replaces common Unicode smart quotes and dashes with their ASCII equivalents so that user input from rich-text editors encodes correctly.
