How Unicode sneaks into your SMS
Text copied from Word, Google Docs, or a website often contains "smart" characters — curly quotes, en/em dashes, non-breaking spaces — that look fine but are not GSM-7. They flip your message to Unicode and double the segment cost. This optimizer swaps them for GSM-7 equivalents automatically.
Frequently Asked Questions
What does the SMS Text Optimizer do?
It replaces non-GSM-7 characters (curly quotes, em dashes, special symbols) with GSM-compatible alternatives so your message stays in the cheaper 160-char encoding.
Will it change my meaning?
No — it maps visually identical characters (e.g. " → ") and only touches encoding-incompatible symbols. Emoji can't be converted and are flagged instead.
