How To Use Our Unicode Checker

Follow these 3 simple steps to instantly identify GSM characters and Unicode symbols from your text messages:

step 1 phone number carrier lookup

Step 1 — Copy and paste a text message into the box. After entering them into the system, the characters from your text message are automatically reflected in the results box.

step 2 phone number carrier lookup

Step 2 — Identify the different symbols in your SMS message. The color distinguishes characters- GSM characters will be displayed in gray, Unicode characters in red, and escape characters in orange.

step 3 phone number carrier lookup

Step 3 — Calculating the characters in your text message. The text counter calculates the number of characters and the number of parts of the split message to control the concatenation.

Benefits of Using a Unicode Character Detector

Identify the Type of Characters

Our detector can quickly distinguish GSM characters from Unicode symbols in your text messages.

Calculate the Number of Characters

The tool can identify the number of characters in the text message and accordingly determine its segmentation.

Remove Unicode Symbols

After analyzing the text, our detector determines which are the Unicode symbols and proceeds to replace them with GSM characters.

Text Division Control

Our detector sets the character limit of the text message with Unicode symbols. It determines the parts into which it will be split in a preview.

Why is it essential to use the Unicode detector?

Our Unicode detector aims to ensure that the information sent by text message is transmitted correctly through a proper encoding.

The problem is that most of these characters are very difficult to encode as they are GSM 3.38 characters, so many providers have stopped offering this work. For that reason, Genvoice Telecom built the Unicode Character Detector tool to help you avoid unnecessary sending costs and ensure that your messages are delivered as intended.

Why does the tool remove Unicode symbols?

The reason is simple, the Unicode character, apart from causing text splitting. It does not allow these types of messages to be seen or, in some cases, may appear as dreaded.

Why are text messages containing Unicode symbols split?

Suppose you want to send text messages with symbols not part of GSM characters. In that case, it is necessary to use Unicode, which assigns a specific code to each character that is not identified as standard characters.

Because several GSM characters are used to replace a Unicode character. You can only send text messages containing 35 to 70 characters, so you generally divide the content of the information you want to send into several messages.

Can I avoid segmenting my text messages and still use Unicode symbols?

Yes, it is possible. For example, you can use the text transliterator to avoid segmentation of your text message and convert Unicode symbols only to Latin.

GSM characters describe the protocols for cellular networks and second-generation mobile devices. These are currently the standard used for mobile communications, covering approximately 90% of the market control. For this reason, messages sent to such devices have to have content adapted to standard GSM characters.

When sending a text message with non-GSM characters, they are limited to only 70 characters. The solution to avoid such a division in your texts is to use the tool to check the Unicode characters and replace them with GSM characters (if there is an equivalent).

Which characters are part of the GSM character set?

The standard character set has letters that are part of the English alphabet, digits, and some special characters, including some Greek characters.

What characters are part of the Unicode characters?

Unicode characters are symbols from the Cyrillic, Chinese, Arabic, Korean, and Hangul alphabets. In addition, they have various special symbols, such as emoticons, emoji, and kanji.

What characters generally cause an SMS to be sent in Unicode?

In some cases, a text message may not appear to have Unicode characters, but it is sent as Unicode. This is likely to happen because characters are frequently copied and pasted from word processing packages such as Microsoft Word. Such characters are usually commas and apostrophes and, in some cases, double quotes.

 GSM commas and apostrophes are identified as single vertical lines. In Word formatting, they are characters with a curve to the left.
