The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Convert a plain Unicode text to an SMS compatible

Asked by loggindevelop in Global System for Mobile Communications (GSM), Scripting Languages, WebApplications

Tags: unicode, sms, unicode to sms, gsm, utf-16, utf-8, ucs2, ucs-2, ucs 2, utf 16, ut

Hello,

I'm developing a PHP application for sending SMS via a Clickatell Gateway, but my problem is I don't know how to encode the Unicode text the user writes into an SMS compatible. I mean, for example: there's a text box where you can write in whatever language you want to with any symbols and so on... When you click send, as the GSM-7 encoding hasn't got all the characters of all the languages, my application has to convert that plain text into a UTF-16 encoding so the SMS which has to be sent will arrive and look as the original written text. Anyway, I'm not sure if the proper encoding is UTF-16. I just want that the text the user types arrives to the mobile phone without changing, being the same as the written one.

Clickatell offers an online converter, but doesn't give the script for free, so I cannot use it from my PHP app. However, I leave a screenshot of the converter and the script I'm currently using.

The final result has to look like 00480065006C006C006F002C0... => (Hello, this is just a test)
