I am working on a php code as shown below which prints H

echo substr("Hello world",0, 1);

Now, I have an accented Ĥ in Ĥello. The following code prints �.

echo substr("Ĥello world",0, 1);

Problem Statement:

I am wondering what changes I should make in the second echo statement above with Ĥello world as the string so that it prints H instead of �.

Note: I want the second echo statement to return H not Ĥ. Only H

I have used the following code but it seems to return Ĥ not H

echo mb_substr("Ĥello world",0, 1);

have you tried `mb_substr("hello world",0,1,"utf-8")` ? – danish-khan-I Jun 20 '19 at 05:10
Its printing blank in my code. – flash Jun 20 '19 at 05:17
Although, its working fine here http://www.writephponline.com/ – flash Jun 20 '19 at 05:19
for me both `substr()` and `mb_substr()` return `H` and not `Ĥ` – danish-khan-I Jun 20 '19 at 05:35
which php version are you using? can you tell in brief about your environment? – danish-khan-I Jun 20 '19 at 05:36
Can you send me the o/p in fiddle like the way Alive has sent ? – flash Jun 20 '19 at 05:36
In your comment above, you are using h not accented h. – flash Jun 20 '19 at 05:39
To what purpose are you doing this? – Qirel Jun 20 '19 at 05:39
`echo substr("Ĥello world",0, 1);` you have `Ĥ` in your code and you want to convert it to `H`. am i right? – danish-khan-I Jun 20 '19 at 05:41
@danish yes, can it be possible through substr() ? – flash Jun 20 '19 at 05:42
@Qirel Here is my actual code https://3v4l.org/jKsiW The place where I am using `echo $title_char;` I want this echo return non-accented characters. – flash Jun 20 '19 at 05:51
But for what purpose are you doing this? What's the underlying reason for wanting to replace data? Is it because you are having encoding issues (so Ĥ is printed as �)? – Qirel Jun 20 '19 at 05:52
you need to have a look at [this](https://stackoverflow.com/questions/6837148/change-foreign-characters-to-their-normal-equivalent) – danish-khan-I Jun 20 '19 at 05:53
