SMS character limit and segment counter
A plain SMS fits in 160 characters, but only when every one of them belongs to the GSM-7 alphabet. One character outside it is enough for the whole message to switch to UCS-2, with a limit of 70. The counter opens with a sample message, detects the encoding and counts the segments a carrier would bill.
Exactly at the single-segment limit.
Past 160, each segment holds 153.
à and lowercase ç do not exist in GSM-7.
70 still fits in one segment; 71 does not.
The € costs 2 septets, but stays under 160.
Yes. The tool gathers the most-used digital-writing metrics in a single panel, characters with and without spaces, words, unique words, lines, paragraphs, sentences and code points, plus estimates of reading and speaking time. That way you compare length, structure and pace of the text without switching between several tools, and everything updates with each keystroke you type.
Because a character outside the GSM-7 alphabet, such as ã, lowercase ç or an emoji, switches the whole message to UCS-2, which has a limit of 70 (and 67 per segment when it goes past that).
Each segment of a concatenated message spends 7 characters on a reassembly header. That is why 160 becomes 153 in GSM-7, and 70 becomes 67 in UCS-2.
The 127 of the basic alphabet and 10 extension ones (^ { } \ [ ] ~ | € and the form feed). The extension ones cost 2 septets each. The full list is in the GSM 03.38 standard.
SMS in GSM-7: 90 septets, 1 segment of up to 160 characters each.
