## Usage

### GSM-7 conversion

```elixir

iex> GSM.to_gsm("foo")

"foo"

iex> GSM.to_gsm("bar :]")

"bar :\e>"

iex> GSM.to_gsm("баz")

** (GSM.BadCharacter) Unsupported GSM-7 character: "б"

```

### GSM-7 validation

```elixir

# Test if valid GSM string

iex> GSM.valid?("foo :]")

true

iex> GSM.valid?("баz")

false

# Test if 2-byte GSM character

iex> GSM.double?("|")

true

iex> GSM.double?(":")

false

```

### UTF-8 conversion

```elixir

iex> GSM.to_utf8("foo :\e>")

"foo :]"

iex> GSM.to_utf8("∫")

** (GSM.BadCharacter) Unsupported GSM-7 character: "∫"

```
